Inelastic Effects in Low-Energy Electron Reflectivity of Two-dimensional Materials
Qin Gao, P. C. Mende, M. Widom +1
A simple method is proposed for inclusion of inelastic effects (electron absorption) in computations of low-energy electron reflectivity (LEER) spectra. The theoretical spectra are…
Theory of Graphene-Insulator-Graphene Tunnel Junctions
S. C. de la Barrera, Qin Gao, R. M. Feenstra
Graphene-insulator-graphene vertical tunneling structures are discussed from a theoretical perspective. Momentum conservation in such devices leads to highly nonlinear current-volt…
Formation of a Buffer Layer for Graphene on C-face SiC{0001}
Guowei He, N. Srivastava, R. M. Feenstra
Graphene films prepared by heating the SiC(000-1) surface (the C-face of the {0001} surfaces) in a Si-rich environment are studied using low-energy electron diffraction (LEED) and…
Friedel Oscillation-Induced Energy Gap Manifested as Transport Asymmetry at Monolayer-Bilayer Graphene Boundaries
Kendal W. Clark, X. -G. Zhang, Gong Gu +4
We show that Friedel charge oscillation near an interface opens a gap at the Fermi energy for electrons with wave vectors perpendicular to the interface. If the Friedel gaps on two…
