Chirality-induced Dynamic Kohn Anomalies in Graphene
Wang-Kong Tse, Ben Yu-Kuang Hu, S. Das Sarma
We develop a theory for the renormalization of the phonon energy dispersion in graphene due to the combined effects of both Coulomb and electron-phonon (e-ph) interactions. We obta…
Coulomb Drag in Graphene
Wang-Kong Tse, Ben Yu-Kuang Hu, S. Das Sarma
We study the Coulomb drag between two single graphene sheets in intrinsic and extrinsic graphene systems with no interlayer tunneling. The general expression for the nonlinear susc…
Self-consistent calculation of ionized impurity scattering in semiconductor quantum wires
Ben Yu-Kuang Hu, S. Das Sarma
We calculate the electron elastic mean free path due to ionized impurity scattering in semiconductor quantum wires, using a scheme in which the screened ionized impurity potential…
Enhancement of the decay rate of nonequilibrium carrier distributions due to scattering-in processes
B. A. Sanborn, Ben Yu-Kuang Hu, S. Das Sarma
We show that, for some semiconductor devices and physical experiments, processes which scatter electrons {\em into} a state can contribute strongly to the decay o…
Many-body exchange-correlation effects in the lowest subband of semiconductor quantum wires
Ben Yu-Kuang Hu, S. Das Sarma
We consider theoretically the electron--electron interaction induced exchange-correlation effects in the lowest subband of a quasi-one-dimensional GaAs quantum wire structures. We…
