Screening of the band gap in electrically biased bilayer graphene: From Hartree to Hartree-Fock
Jack N. Engdahl, Zeb E. Krix, Oleg P. Sushkov
It is well known that a direct band gap may be opened in bilayer graphene via the application of a perpendicular electric field (bias). The bias and the chemical potential are cont…
Theory of Band Gap Reduction Due to Conduction Electrons in 2D TMDs: Imaginary Frequency Formalism
Jack N. Engdahl, Harley D. Scammell, Dmitry K. Efimkin +1
Two Dimensional (2D) Transition Metal Dichalcogenides (TMDs) possess a large direct band gap which has been experimentally observed to shrink with increasing charge carrier density…
Excitons in Atomically Thin TMD in Electric and Magnetic Fields
Jack N. Engdahl, Harley D. Scammell, Dmitry K. Efimkin +1
The magnetic field dependence of photoabsorption provides direct insights into the band structure of semiconductors. It is perhaps surprising that there is a large discrepancy betw…
Driving Viscous Hydrodynamics in Bulk Electron Flow in Graphene Using Micromagnets
Jack N. Engdahl, Aydın Cem Keser, Thomas Schmidt +1
We consider the hydrodynamic flow of an electron fluid in a channel formed in a two-dimensional electron gas (2DEG) with no-slip boundary conditions. To generate vorticity in the f…
