I am interested in investigating the electronic, optical and spin dependent properties of novel quantum materials like two-dimensional materials and their devices. I have expertise in controlling the properties of 2D materials using atomic scale modifications (adatoms, hetero-structures, proximity effects, etc.) with an intent to tweak their properties on demand, as well as explore novel physical phenomenons emerging due to such modifications. To achieve this, my research focuses on growth of novel quantum materials using molecular beam epitaxy (MBE) techniques and state-of-the-art characterization tools. We utilize a unique in-situ low temperature ultra-high vacuum magneto-transport measurement setup with capabilities to evaporate controlled amount of adatoms, and simultaneously perform quantum transport, Raman and photoluminsence spectroscopy on devices. In addition, we study the electronic band structure of mesoscopic sized quantum materials and devices using in-operando NanoARPES with a spatial resolution reaching upto 50 nm at MASTERO beamline in Advanced light source.

What molecular properties give rise to a strong piezoelectric response?

  • By Burcu Ozden
  • 22 November 2017

In this study Geoffrey R. Hutchison and his colleagues tried to answer the question of " What molecular properties give rise to a strong piezoelectric response?"  To do so, they systematically probe the interplay among peptide chemical structure, folding propensity, and piezoelectric properties, uncovering in the process new insights into the origin of peptide electromechanical response. They have designed variety of peptides and peptoids and test the effect of molecular properties on piezoelectric response via serious measurements including ircular dichroism (CD), Polarization-modulated infrared reflection−absorption spectroscopy (PM-IRRAS), tomic force microscopy (AFM), piezo-force microscopy (PFM), and X-ray photoelectron spectroscopy (XPS) measurements. They showed backbone rigidity is an important determinant in peptide electromechanical responsiveness. 

New Era in Thermal Scanning Probe Lithography

  • By Burcu Ozden
  • 15 November 2017

Tevis Jacobs and his collaborators from IBM and SwissLitho were achieved sub-10 nanometer feature size in Silicon using thermal scanning probe lithography. In this work, they  the t-SPL parameters that influence high-resolution patterning on the transfer stack and demonstrate that sub-15 nm half-pitch resolution patterning and transfer by t-SPL are feasible. They found that the resolution in t-SPL is limited by the extent of the plastic zone in thermo-mechanical indentation on the pattern transfer stack because, at temperatures approaching the resist’s decomposition temperature, the line shape widens, reducing the achievable resolution. They achieved reliable transfer of patterned dense lines down to 14 nm half-pitch and in the best case 11 nm half-pitch. Furthermore, evidently they showed that an enhanced resolution below 10 nm half-pitch might be possible on a mechanically different transfer stack.

The Ability to Electrically Tune the Dimensionality of mesoscopic LAO/STO Channels

  • By Burcu Ozden
  • 27 October 2017

In this work, authors used conductive atomic force microscope (c-AFM) lithography in which the conduction is controlled by surface protons that are distributed on the LAO surface. They have created two conducting channel with varying witdhs as 10 and 200nm on a  LAO/STO heterostructures grown by pulsed-laser deposition. They designed the the devices in a way that two conducting channels connected in series with two leads and voltage probes. By using silver epoxy on the bottom of the STO substrate they created contacts for a back gate voltage. They investigated changes in the magnetotransport properties on the channels with different widths by varying back gate voltage and applied magnetic field. They measured the conductance for both narrow and wide channels and demonstarted the hysteresis of both channels with back gating. Saturation of the conductance at higher gate voltages was also shown. They were able to demonstrate dimensional crossover from 2d to 1D behavior with their magnetoconductance measurements.

New Technique for Measuring the Layer-Resolved Charge Density

  • By Burcu Ozden
  • 25 October 2017

Recently Benjamin M. Hunt and his colleagues developed a new technique for measuring the layer-resolved charge density, from which they can map layer polarization of the valley or spin quantum numbers in bilayer graphine and other two dimensional materials. In this study, they demonstrated direct measurement of valley and orbital levels in bilayer graphite. They have detected that the four valley and orbital components have different weights on the two layers of the bilayer. By using Hunt’s technique one can probe layer, valley, and spin polarization quantitatively in other atomic layered materials, including twisted bilayer graphene and both homobilayer and heterobilayer of transition metal dichalcogenide

Our group studies the role of external electromagnetic fields, such as microwave and millimeter waves in accessing regions of the free energy/phase space diagram of a material, hitherto unavailable to conventional synthesis routes. Examples include structurally integrated ordered-disordered ceramic oxides and oxide-polymer composites with unexpected electronic and mechanical properties, adaptive oxides for resistive switching, supersaturated mixed oxide solid solutions with hierarchical structure. An additional benefit involves employing low temperatures for directly processing such materials on fibers and flexible, light-weight substrates for applications in sensing and energy harnessing, storage.

We have extensive experience in the synthesis of inorganic and organic thin films using solution based sol-gel/microwave-assisted synthesis and chemical vapor deposition (CVD) polymerization. We carry out microscopic, spectroscopic and analytical characterization of thin films, as well micro/nano-fabrication processes for building and testing of photovoltaic, battery, and sensing devices.

Professor Gellman's group uses experimental methods to study processes occurring on surfaces such as the bonding of molecules to metal surfaces, surface structure, reaction kinetics, catalysis, friction, and lubrication.  The use of surface science methods to create and study well-defined surfaces allows Professor Gellman's group to investigate surface chemistry relevant to these processes at the most fundamental level.

Professor Gellman’s group has pioneered the study of enantioselective surface chemistry on naturally chiral metal surfaces.  These surfaces are high Miller index planes that lack mirror symmetry and therefore exist as two enantiomorphs.  Recent work using D- and L-tartaric acid adsorbed on several Cu(hkl)R&S surfaces has demonstrated that one can achieve enormously high enantiospecific reaction rates via autocatalytic surface explosion mechanisms. Other work has used 13C isotopically labelled L-aspartic acid to monitor directly the enantioselective separation of DL-aspartic acid on Cu(3,1,17)R&S surfaces.  This work generates insight into some of the fundamental phenomena that lead to enantioselective adsorption and catalysis on chiral surfaces.

Recent work in Professor Gellman’s laboratory has focussed effort on the development of instrumentation and methods for high throughput study of surface phenomena.  Study of the surface science of multicomponent materials such as alloys is complicated by the fact that one needs to prepare, characterize and study many samples of varying composition.  Gellman’s group has worked to overcome this bottleneck by developing tools for the preparation of Composition Spread Alloy Films.  These are alloy films that have composition gradients parallel to their surfaces such that a 1x1 cm2 sample contains all possible compositions of a ternary alloy, AxByC1-x-y with x = 0 -> 1, y = 0 -> 1-x.  Spatially resolved materials and surface characterization methods (SEM, EDX, EBSD, XPS, UPS, LEIS, etc.) can then be used to map and study composition dependent phenomena such as surface segregation, catalysis, dewetting, and oxidation across the entire alloy composition space.

Another body of recent work exploits the use of spherically curved single crystal surfaces to conduct high throughput studies of structure sensitive surface chemistry that span surface orientations continuously.  This circumvents the need for study of many single crystals exposing surfaces of a single crystallographic orientation.  Surface Structure Spread Single Crystals expose a distribution of different surface orientations spanning a continuous region of the stereographic projection of all possible surface orientations.  Spatially resolved surface analysis methods such as STM, XPS and UPS can be used to study problems in surface structure, surface physics and structure sensitive surface chemistry

Owing to the recent development of material growth methods including the pulsed laser deposition (PLD) and molecular beam epitaxy (MBE), atomically sharp interfaces between materials become available. At these interfaces, the electron-electron interaction is greatly enhanced, leading to novel phases including metal-insulator transition,  superconductivity, magnetism and spin-orbit interaction.

A notable example is the (001) LaAlO3/SrTiO3 (LAO/STO) interface, where a polar discontinuity drives electronic interface reconstruction and leads to a 2D electron liquid (2DEL) at the interface. The interface conductivity is critically dependent on the LAO thickness. Below a critical thickness 4 unit cell the interface is insulating, otherwise the interface is conducting.

Since the discovery of the 2DEL in 2004[1], intense interests have been casted on this area.  Up to now, the knowledge on this interface is growing rapidly, and so do the debates. The 2DEL is gate tunable, with a critical LAO thickness dependence[2]. The interface is superconducting, an inherent property of STO[3, 4]. More interestingly, it has a similar superconducting phase diagram as the high-Tc superconductor. Although both LAO and STO are non-magnetic, the interface is magnetic[5, 6].  More interestingly, magnetism and superconductivity can co-exist[7-9]. Owing to the inversion symmetric breaking, the interface has strong tunable spin-orbit interaction[10, 11]. Provided all these interesting phases, we invented the conductive-AFM lithography method that allows us to fabricate nanostructures on demand, effectively programing all these properties into nanoscale. Indeed, it is fun to watch all these properties interplay at nanoscale.
