Intersubband plasmons in quasi-one-dimensional electron systems on a liquid helium surface
Marcos R. S. Tavares, G. -Q. Hai, F. M. Petters +1
The collective excitation spectra are studied for a multisubband quasi-one-dimensional electron gas on the surface of liquid helium. Different intersubband plasmon modes are identi…
Carrier relaxation due to electron-electron interaction in coupled double quantum well structures
Marcos R. S. Tavares, G. -Q. Hai, S. Das Sarma
We calculate the electron-electron interaction induced energy-dependent inelastic carrier relaxation rate in doped semiconductor coupled double quantum well nanostructures within t…
Intrasubband and Intersubband Electron Relaxation in Semiconductor Quantum Wire Structures
Marcos R. S. Tavares, S. Das Sarma, G-Q. Hai
We calculate the intersubband and intrasubband many-body inelastic Coulomb scattering rates due to electron-electron interaction in two-subband semiconductor quantum wire structure…
Inelastic Coulomb scattering rates due to acoustic and optical plasmon modes in coupled quantum wires
Marcos R. S. Tavares, Guo-Qiang Hai
We report a theoretical study on the inelastic Coulomb scattering rate of an injected electron in two coupled quantum wires in quasi-one-dimensional doped semiconductors. Two peaks…
Tunneling-Assisted Acoustic Plasmon-Quasiparticle Excitation Resonances in Coupled Q1D Electron Gases
Guo-Qiang Hai, Marcos R. S. Tavares
We show that a weak non-resonant tunneling between two quantum wires leads to splitting of the acoustic plasmon mode at finite wavevector. Two gaps open up in the dipersion of the…
Inelastic Coulomb scattering rate of a multisubband Q1D electron gas
M. Tavares, G. -Q. Hai
In this work, the Coulomb scattering lifetimes of electrons in two coupled quantum wires have been studied by calculating the quasiparticle self-energy within a multisubband model…
