Systematic theoretical studies of Raman spectra of \(\mathrm{GaAs}-\mathrm{Al}_{x} \mathrm{Ga}_{1-x} \mathrm{As}\) superlattices are presented. The electronic states are described by an envelope-function method and the phonon modes are described in a microscopic rigid-ion model. Both resonant and no

We investigate the existence of a band structure in GaAs/Al x Ga 1-x superlattices with cylindrical symmetry, namely GaAs/Al x Ga 1-x As cylindrical superwires. These systems consists of a large number of concentric GaAs and Al x Ga 1-x As alternate cylindrical shells around a central GaAs cylindric
## Abstract This paper is concerned with the investigation of the peculiarities of the application of liquid phase epitaxy for obtaining multilayer structures with heterojunctions in the AlAs–GaAs system. Segregational depletion of Al in liquid and in solid phases is characteristic of this system.
Reflectance ( \(R\) ) and thermoreflectance (TR) of quantum well structures grown by MBE have been investigated at low temperature ( \(30 \mathrm{~K}\) ) in order to demonstrate the capabilities of \(T R\) to study quantum confined systems. Our results show that low temperature \(T R\) is a simple a
