Our team engaged in cutting-edge investigations at the Quantum Materials and Device Research Laboratory (QMDrL). Their work revolves around several key areas:
Exploration of 2D Quantum Materials: Our team is dedicated to unravelling the unique properties of two-dimensional (2D) quantum materials, with a particular emphasis on their fabrication, characterization and potential in emerging Quantum technologies.
2D and van der Waals Heterostructure Fabrication: They specialize in creating both lateral and vertical multi-junction heterostructures using 2D Transition Metal Dichalcogenides, focusing on precise atomic engineering at the nanoscale both by CVD and mechanical exfoliation method and examining the interfaces and interactions between different 2D materials.
Excitons: We explore different excitons, including moire excitons, which are fundamental energy carriers in 2D materials, investigating their properties and applications.
Nanoscale Device Physics: Their research involves the study of the intricate physics at the nanoscale, seeking to understand and manipulate device behaviour at these tiny dimensions. Utilizing advanced techniques, they carry out in-depth electronic and optical characterizations of the materials and devices they create.
Quantum Phase Engineering: The team is actively involved in quantum phase engineering, a critical aspect of harnessing the quantum properties of 2D materials for technological advancements.
Optoelectronic Device Development: Their work extends to developing innovative optoelectronic devices, focusing on applications in quantum emitters, photovoltaics, and sensors.
Synergistic Platform Creation: Our vision is to establish a synergistic platform where various scientific disciplines at the nanoscale converge. This interdisciplinary approach aims to bridge the gap between fundamental scientific discoveries and developing cutting-edge technologies.Dr. Sahoo's research group is dedicated to exploring the extraordinary potential of 2D quantum materials and their heterostructures, applying their findings to advancing optoelectronic devices, and fostering collaborative endeavours that transcend traditional scientific boundaries.

We welcome highly motivated Master, Doctoral and Post-Doctoral research scholars as well as undergards to join our lab.
