The effects of microscopic scattering on terahertz third harmonic generation in monolayer graphene
Parvin Navaeipour, Marc M. Dignam
Due to its linear dispersion, monolayer graphene is expected to generate a third harmonic response at terahertz frequencies. There have been a variety of different models of this e…
Pump-induced terahertz anisotropy in bilayer graphene
Angelika Seidl, Roozbeh Anvari, Marc M. Dignam +5
We investigate the intraband nonlinear dynamics in doped bilayer graphene in the presence of strong, linearly-polarized, in-plane terahertz fields. We perform degenerate pump-probe…
The impact of nitrogen doping on the linear and nonlinear terahertz response of graphene
Roozbeh Anvari, Eugene Zaremba, Marc M. Dignam
It is well known that impurities play a central role in the linear and nonlinear response of graphene at optical and terahertz frequencies. In this work, we calculate the bands and…
Valley-polarization in biased bilayer graphene using circularly polarized light
Alex Friedlan, Marc M. Dignam
Achieving a population imbalance between the two inequivalent valleys is a critical first step for any valleytronic device. A valley-polarization can be induced in biased bilayer g…
The effect of microscopic scattering on the nonlinear transmission of terahertz fields through monolayer graphene
L. G. Helt, M. M. Dignam
We consider the nonlinear terahertz response of n-doped monolayer graphene at room temperature using a microscopic theory of carrier dynamics. Our tight-binding model treats the ca…
Nonlinear response of biased bilayer graphene at terahertz frequencies
Riley McGouran, Marc M. Dignam
A density-matrix formalism within the length gauge is developed to calculate the nonlinear response of both doped and undoped biased bilayer graphene (BBLG) at terahertz frequencie…
