The phase transition in VO2 probed using x-ray, visible and infrared radiations
Suhas Kumar, John Paul Strachan, A. L. David Kilcoyne +5
Vanadium dioxide (VO2) is a model system that has been used to understand closely-occurring multiband electronic (Mott) and structural (Peierls) transitions for over half a century…
Atomic Batteries: Energy from Radioactivity
Suhas Kumar
With alternate, sustainable, natural sources of energy being sought after, there is new interest in energy from radioactivity, including natural and waste radioactive materials. A…
Sequential Electronic and Structural Transitions in VO2 Observed Using X-ray Absorption Spectromicroscopy
Suhas Kumar, John Paul Strachan, Matthew D. Pickett +3
The popular dual electronic (Mott) and structural (Peierls) transitions in VO2 are explored using x-ray absorption spectromicroscopy with high spatial and spectral resolutions. It…
Fundamental Limits to Moore's Law
Suhas Kumar
The theoretical and practical aspects of the fundamental, ultimate, physical limits to scaling, or Moore-s law, is presented.
Characterization of electronic structure of periodically strained graphene
Marjan Aslani, C. Michael Garner, Suhas Kumar +3
We induced periodic biaxial tensile strain in polycrystalline graphene by wrapping it over a substrate with repeating pillar-like structures with a periodicity of 600 nm. Using Ram…
Local Temperature Redistribution and Structural Transition During Joule-Heating-Driven Conductance Switching in VO2
Suhas Kumar, Matthew D. Pickett, John Paul Strachan +3
Joule-heating induced conductance-switching is studied in VO2, a Mott insulator. Complementary in-situ techniques including optical characterization, blackbody microscopy, scanning…
