Device Physics of Two-Dimensional Crystalline Materials
The study of two-dimensional (2D) electrons in condensed matter physics has two milestones: quantum Hall effects in semiconductor heterostructures and superconductivity in cuprates. In both, the 2D electrons are embedded in complex material structures. The discovery of graphene allows for the isolation of 2D electrons in their ...
Gas Adsorption on Suspended Carbon Nanotubes and Graphene
Rare gas adsorption was studied on suspended individual single walled carbon nanotubes and graphene. The devices were fabricated as field effect transistors. Adsorption on graphene was studied through two-terminal conductance. On nanotube devices adsorption was studied through conductance while the coverage (density) of the ...
