About Us

We are a research group based in Rutgers University Physics Department in Piscataway, New Jersey, where we study the physics of novel semiconductors. Our research tends to revolve around the following themes:

Fundamentals of charge carrier transport in organic semiconductors (OFETs).
The fundamental optical properties of highly ordered organic semiconductors (exciton dynamics, photo-conductivity and the photovoltaic effect).
Molecular self-assembly at functional interfaces.
Novel inorganic layered semiconductors (dihalcogenides and graphene).
