Research Interests

I am interested in investigating the electronic, optical and spin dependent properties of novel quantum materials like two-dimensional materials and their devices. I have expertise in controlling the properties of 2D materials using atomic scale modifications (adatoms, heterostructures, proximity effects, etc.) with an intent to tweak their properties on demand, as well as explore novel physical phenomenons emerging due to such modifications.

My research focuses on growth of novel quantum materials using molecular beam epitaxy (MBE) techniques and state-of-the-art characterization tools. We utilize a unique in-situ low temperature ultra-high vacuum magneto-transport measurement setup with capabilities to evaporate controlled amount of adatoms, and simultaneously perform quantum transport, Raman and photoluminsence spectroscopy on devices. In addition, we study the electronic band structure of mesoscopic sized quantum materials and devices using in-operando NanoARPES with a spatial resolution reaching up to 50 nm at MASTERO beamline in Advanced light source.
