T. Furuta et al., ENERGY RELAXATION PROCESS OF PHOTOEXCITED ELECTRONS IN GAAS ALGAAS QUANTUM-WELL STRUCTURES/, Semiconductor science and technology, 9(5), 1994, pp. 453-455
The energy relaxation process is successfully measured for various qua
ntum well structures. The measurements show a marked difference from b
ulk characteristics as the well width becomes narrower. This implies t
hat the two-dimensional nature of carriers plays an important role in
the energy relaxation process. Monte Carlo simulation results support
the experimental findings.
