Electron Transfer without Overcoming a Barrier

  • By Burcu Ozden
  • 14 February 2018

In the recently accepted paper in Physical Review Letter, Hrvoje Petek and his colleagues investigate the coherent electron transfer from an interface state that forms upon chemisorption of Ag nanoclusters onto graphite to a σ symmetry interlayer band of graphite. Interfacial charge transfer is a fundamental process in heterogeneous and plasmonically enhanced catalysis. The charge transfer, however, is thought to be restrained by an interfacial potential barrier, such as a Schottky barrier at a metal-semiconductor interface. With optical excitation, the interfacial charge transfer can also be efficiently completed by coherent dipole coupling between the donor and acceptor bands. In this study Petek and his colleagues advance the time-resolved multidimensional multiphoton photoemission spectroscopy technique to not only pump the donor band and probe the acceptor band, but also directly image the coherent polarization dynamics between them. They discover a direct resonant electron transfer channel where two-photon absorption couples a donor interface state formed by electron delocalizing from Ag clusters to graphite and the acceptor state, which is the unoccupied interlayer band of graphite. Such electron transfer can be driven instantaneously by two photon absorption and is completed within the electron-hole dephasing time of ~10 fs.

On behalf of the Secretary of the Air Force, the Air Force Research Laboratory (AFRL) began a review of the US Air Force science and technology strategy to maintain its technological advantage and meet the national security challenges of 2030 and beyond. To support this effort, AFOSR, the basic research directorate of AFRL, is reaching out to its community across the US to capture a diversity of ideas.

  • 9 February 2018

The International Day of Women and Girls in Science, celebrated each year on 11 February, was adopted by the United Nations General Assembly to promote full and equal access to and participation in science for women and girls. This Day is a reminder that women and girls play a critical role in science and technology communities and that their participation should be strengthened. The celebration is led by UNESCO and UN-Women, in collaboration with institutions and civil society partners that promote women and girls' access to and participation in science.

Quantum Frontiers and Fundamentals 2018” is an international conference that will be held from 30 April to 4 May 2018 in Bangalore (India), hosted by the Raman Research Institute.
The Conference will involve both experimental and theoretical aspects concerning recent advances in fundamental quantum mechanical issues like quantum superposition, quantum entanglement, testing quantum mechanics in the macroscopic regime, wave particle duality, nonlocality, contextuality, generalized quantum measurements and quantum information tasks in systems such as photons, electrons, neutrons, ions, and molecules.

Susan Fullerton and colleagues are one of five winners of international circular materials challenge

  • By Burcu Ozden

Each year more than eight million tons of plastics pollute the ocean, forming mammoth, so-called “garbage patches” via strong currents. Even with new collection methods, only 0.5 percent out of that volume is currently removed from the seas. One solution to this growing crisis is to prevent plastic from becoming waste, to begin with – and Susan Fullerton and colleagues are one of five international teams awarded for their novel solutions to this problem. The group was one of two winners in Category 1: “Make unrecyclable packaging recyclable,” and proposes using nano-engineering to create a recyclable material that can replace complex multi-layered packaging – mimicking the way nature uses just a few molecular building blocks to create a huge variety of materials.


Segregation-induced ordered superstructures

  • By Burcu Ozden
  • 24 January 2018

Michael Widom and his colleagues showed what happens at the grain boundaries of one particular alloy of the metals nickel and bismuth that makes it brittle in their paper published in Science. Using advanced electron microscopes, Widom’s collaborators at Lehigh University scrutinized these microscopic grain boundaries at an atomic level. In a "very heroic experimental program" they discovered that when grains met, the bismuth and nickel atoms realigned into lattices to form layered superstructures at the grain boundaries. These superstructures had previously been thought to exist only rarely in some alloys. Finding it at many different boundaries led the team to conclude that these superstructures are probably much more common than many people had thought. 


Finding Funding: Resources & Opportunities for New Researchers

  • 24 January 2018

An introductory session to Pivot led by Ryan Champagne from the Office of Research and Robin Kear from the University Library System. The hands-on session will provide an overview of this resource and how it may be used to find funding and collaboration opportunities to support your research. Additional resources related to funding competitions coordinated within the University, as well as funding programs for early career faculty, will also be presented.
