Research focus:
Saroj Dash’s group focuses on Electronic charge, spin and quantum transport in 2D materials such as Graphene, h-BN, MoS2, WSe2, Semiconductors, Topological insulators, Weyl semimetals and van der Waals heterostuctures 2D materials.
Experimental and theoretical methods:
Our group develops different experimental methods for fundamental electronic device physics experiments such as - 1. Fabrication of 2D materials heterostructures and their characterizations, 2. Nanofabrication of electronic, spintronic and optoelectronic devices, 3. Electronic, Spintronic, Quantum and magneto transport measurements.
Focus of future research:
- Graphene/h-BN heterostructures for Nanoelectronic, Spintronic and Quantum devices.
- 2D Semiconductor (MoS2, WSe2) heterostcture devices (EFTs, Tunnel FETs, Solar cells, LEDs)
- Topological insulators and Weyl-semimetals based Quantum devices.
- 2D materials van der Waals heterostructure based Nanoelectronic and Quantum devices
