We developed a theory of magnetophonon resonance (MPR) in quantum wells in a tilted magnetic field. We explain the existence of two peaks of MPR in its angular dependence that may be very sharp. A relation between the MPR amplitude in the perpendicular magnetic field and its theta-dependence in a tilted field is discussed. We come to conclusion that the theta-dependence of MPR can give valuable information concerning the optic ...
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 ...
