Researcher Spotlight

Dr. Ravindra Pandey

Professor, Physics

Ravindra Pandey 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.
