Dr. Ravindra Pandey
Professor, Physics
Two dimensional (2D) materials have stimulated an avalanche
of investigations to exploit their novel properties for the
applications at nanoscale. Many new 2D materials are emerging
in recent years as possible building blocks for future
electronic devices, such as graphene, transition metal
dichalcogenides (TMDs), layered transition oxides, hexagonal
boron nitrides (h-BN), and topological insulators. These
materials cover metals, semiconductors and insulators,
therefore, could be utilized for various components in
electronic devices.
Dr. Pandey’s
research focuses on searching of novel 2D materials with
different structures and exploring their properties based on
density functional theory (DFT), which is of importance both
for fundamental interests and applications.
The work with Gaoxue Wang, a PhD candidate, considered strain
engineering of Dirac cones in graphyne and stability of
phosphorene oxide.
Apart from searching for possible novel 2D materials,
Dr. Jarvis Loh, an A*STAR International Fellowship Scholar and
a post-doctoral fellow, and Dr. Pandey examined few 2D
materials which have
been synthesized but not yet well-understood. One such material
is molybdenum disulphide (MoS2), which has unique,
intriguing, and functional properties, including a large
carrier mobility 3, and high current-carrying capacity 4.
Specifically, his group is using Superior's computing
power to understand how the quantum mechanical effects in
MoS2 modulate its geometry, energetics and
electronic characteristics, and their layer dependency.
