Phonon Generation by Current-Carrying Nanowires
Abstract
Spectral and spatial distributions of phonons generated in a quantum wire by a transport current are investigated as a function of the voltage across the nanostructure and the gate voltage. We start wfth consideration of the simplest case of a uniform nanowire which connects two thermal reservoirs. Then the role of the leads is discussed. It is shown that both spectral and angular distributions of emitted phonons depend significantly on the bias voltage. Studies of phonon generation allows one to detemine the electron-phonon coupling constant in ballistic devices.
