2D Materials and Devices Group

Department A-Z


Our research deals with fundamental aspects of two-dimensional materials synthesized by chemical exfoliation and chemical vapor deposition. We study: phase engineering of 2D materials; low resistance electrical contacts on 2D semiconductors for high performance electronics; metallic 2D materials for energy storage and electrocatalysis; interfaces between 3D complex oxides and 2D; and chemical functionalization of 2D materials.

Two-dimensional Layered Transition Metal Dichalcogenide

2D transition metal dichalcogenides — with generalized formula of MX2, where M is a transition metal from groups 4–10 elements and X is a chalcogen (S, Se, or Te) — exhibit versatile optical, electrical and electrochemical properties.

2D Semiconductors for Transistors

In state of the art short-channel FETs, leakage current leads to power dissipation in the OFF state due to poor gate electrostatics. In FETs with 2D semiconductors, charge carriers are confined within atomically thin channels and hence are uniformly influenced by the gate voltage – giving rise to excellent gate electrostatics so that OFF state current is reduced.

2D Materials for Electrocatalysis

Our group has developed microelectrochemical cells that allow precise identification of catalytically active sites. We can accurately quantify the catalytic activity from edge sites or the basal plane for the hydrogen & oxygen evolution reactions as well as oxygen, CO2 and N2 reduction reactions.

Interfaces Between 2D Materials and Complex Oxides

The coupling of various degrees of freedom between 2D materials and complex oxides leads to exotic optical and electronic states of matter. Investigation and study of such phenomena is the central theme of this thrust in our group.
