Perturbation theory of the mass enhancement for a polaron coupled to acoustic phonons
Perturbation theory of the mass enhancement acoustic phonons
2010/11/18
We use both a perturbative Green’s function analysis and standard perturbative quantum me-
chanics to calculate the decrease in energy and the effective mass for an electron interacting with acoustic...
The Effect of Non-Equilibrium Acoustic Phonons on the Tunnel Current in GaAs/AlAs Superlattices
Non-Equilibrium Acoustic Phonons Tunnel Current GaAs/AlAs Superlattices
2010/4/16
We present the first study of the effect of ballistic acoustic phonons generated by a heated metal film on the tunnel current in GaAs/AlAs superlattices. The phonon-induced increase of the tunnel curr...
Heat Pulse Studies of the Emission and Absorption of Acoustic Phonons in GaAs Quantum Wells and Wires
heat pulse techniques acoustic phonons
2010/4/16
This paper reviews some recent experiments in which heat pulse techniques have been used to study the interaction of acoustic phonons with electrons in semiconductor quantum wells and wires. Heat puls...
Dispersion relations of acoustic phonons in pyrope garnet: Relationship between vibrational properties and elastic constants
