Prof. Saroj Dash leads a research group with 5 PhD students and 8 Postdocs. <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.chalmers.se/en/departments/mc2/research/quantum-device-physics/saroj-dash-research-group/">https://www.chalmers.se/en/departments/mc2/research/quantum-device-physics/saroj-dash-research-group/</a>Saroj Dash’s research group investigates 2D quantum materials and their hybrid devices for electronic, spin, and quantum technologies. We fabricate nanoscale devices with graphene, semiconductors, magnets, superconductors, topological materials, and their heterostructure to investigate new physics and realize new device concepts. We aim to investigate unique properties by tailoring their crystal and time reversal symmetries, band structure design, tuning Berry curvature and quantum metrics, spin-orbit interactions, proximity-induced effects, and tunability by twist angle control of 2D materials, light, and gate voltages. The use of modern state-of-the-art device fabrication techniques and the development of new methods of materials growth, heterostructure preparation, and characterization of devices with a range of frequencies, temperatures, and magnetic fields are essential parts of our research. The goal is to exploit the spin and quantum properties of electrons in 2D materials and their hybrid structures for the integrating memory and logic devices, sensors, quantum technologies, and neuromorphic computing.
