摘要：
The energy loss rate of hot electrons in a semiconducting freestanding quantum well structure, in the presence of zero and finite quantizing magnetic field, is studied using electron temperature model. Electron interaction with confined acoustic phonons via deformation potential coupling described by elastic continuum model is considered. Numerical results are given for GaN, InAs, and InSb with zinc-blende structure and GaAs freestanding quantum well structures for the dependence of energy loss rate on electron temperature and the magnetic field. The results are compared to those obtained for bulk description of acoustic phonon modes.
