Research Interests

Our experimental research group studies physical properties of low dimensional condensed matter systems. We use advanced nanofabrication techniques combined with controlled sample growth to design and develop sub-micron devices. These devices will be used to explore microscopic mechanisms that influence and/or dictate the fundamental physical properties at the nanometer scale level.

We explore electron transport in oxide nanowire FETs, nanotubes, 2D semiconductors, and other atomic layers under extreme physical conditions: ultra low temperatures (10 mK), high magnetic fields (16 T) and a.c. electric fields (~GHz). Some of our physics interests include metal-insulator transitions, noise spectroscopy near phase transitions, superconductor-insulator transition, microwave spectroscopy to study collective phases in 2D materials etc.
