E. Reyes-gomez et al., The fractional-dimensional space approach to MBE-grown quantum-sized semiconductor low-dimensional systems, J CRYST GR, 227, 2001, pp. 77-82
Shallow impurities and excitons in MBE-grown quantum-sized semiconductor lo
w-dimension;ll systems are studied within the fractional-dimensional space
approach. We present calculations for shallow-donor states in GaAs(Ga,Al)As
quantum wells and superlattices and fur excitons in GaAs- (Ga,AI)As quantu
m wells and symmetric-coupled double quantum wells. Effects of growth-direc
tion applied magnetic fields are also considered. Results are shown to be i
n good agreement with previous variational calculations and available exper
imental measurements. (C) 2001 Elsevier Science B.V. All rights reserved.
