Jyoti Katoch, assistant professor of physics at Carnegie Mellon University, has received a prestigious early career grant from the U.S. Department of Energy (DOE). Katoch’s research focuses on understanding the properties of two-dimensional quantum materials.
The grant will allow Katoch, a condensed matter physicist, and her research group in Carnegie Mellon’s Lab for Investigating Quantum Materials, Interfaces and Devices (LIQUID) to investigate quantum materials using advanced technologies. 2D materials are the thinnest known materials. When these materials are stacked together, they form heterostructures with unique quantum properties, such as superconductivity. By changing the layers of materials, researchers can finely tune the heterostructure’s electronic and physical properties.
Under the DOE grant, Katoch will probe the spatially resolved electronic band structure of 2D quantum materials, including those made by stacking graphene and transition metal dichalcogenides, and engineer the materials’ properties by making nanoscale perturbations in superlattices and adatoms found in the materials’ heterostructures. They will do this by further developing in-operando nanoARPES, an experimental technique that combines spectroscopy and microscopy to study the band structures of quantum systems under non-equilibrium conditions.
