Electronic Structure and Chemical Interactions of Two-Dimensional Material Interfaces
The Johns lab is interested in the study of new two-dimensional (2D) materials for their interesting electronic and optical properties. In particular they are interested in the chemistry of graphene, 2D metal dichalcogenides, and graphane analogues. They use dispersion corrected plane-wave based density functional theory to study the chemical interface between these materials commonly used in device fabrication. They are also exploring the substrate-induced effects on the electronic and optical properties of these materials. By understanding the chemical bonding between semiconducting substrates and 2D materials, they hope to develop new methods of synthesizing heterojunction devices such as LEDs and digital logic gates.
A bibliography of this group’s publications is attached.
