چکیده

We present a temperature-dependence photoluminescence of (GaAs)5/(AlAs)5 superlattice grown on (311)A-oriented semi-insulating substrate by molecular beam epitaxy. The temperature dependence reveals an anomalous decrease of the PL width, which is explained in terms of phonon-assisted thermal activation of localized excitons. q 2004 Elsevier Ltd.

Raman scattering of InAs/AlAs quantum dot superlattices grown on (001) and (311)B GaAs surfaces

We present a comparative analysis of Raman scattering by acoustic and optical phonons in InAs/AlAs quantum dot superlattices grown on (001) and (311)B GaAs surfaces. Doublets of folded longitudinal acoustic phonons up to the fifth order were observed in the Raman spectra of (001)- and (311)B-oriented quantum dot superlattices measured in polarized scattering geometries. The energy positions of ...

Characteristic of P-type AlAs/GaAs Bragg Mirrors Grown by MBE on (100) and (311)A Oriented Substrates

P-type GaAs/AlAs distributed Bragg mirrors have been grown using molecular beam epitaxy on (100) and (311)A GaAs substrates in a similar conditions. A comparison of I-V measurements shows that the resistance of the ungraded mirrors grown on the (311)A substrate is 35 times lower than those grown on the (100) substrate with similar structure. The effective barrier heights for both (311 )A and (1...

Confined electron states in corrugated GaAs/AlAs superlattices

The electronic and optical properties of GaAsIAlAs superlattices grown in the [311] direction are investigated in the framework of an empirical tight-binding model which includes second-neighbor interactions. The [3 111 superlattices are of great interest because of their non-flat interfaces and because the periodic corrugation which appears gives rise to a lateral confinement. This results in ...

Influence of various growth parameters on the interface abruptness of AlAs/GaAs short period superlattices

Cross-sectional scanning tunneling microscopy has been used to investigate the effects of several key growth parameters on the resulting interfacial quality of AlAs/GaAs short period superlattices. For growth on top of AlGaAs layers, only superlattices grown with periodicity no smaller than 4 unit cells of GaAs and 2 unit cells of AlAs and grown with a minimum of 30 s of growth interrupt time a...

Effects of D-Doping on Characteristics of AlAs/GaAs Barriers Grown by Mba at 400 ??C

Effects of d-doping on barriers effective heights and series resistance of highly doped n-type GaAs/AIAs/GaAs/AlAs/GaAs heterostructures, grown by molecular beam epitaxy (MBE) at 400?°C, have been studied. As it was expected, inclusion of an n+ d-doped layer at each hetero-interface has reduced the barriers heights and series resistance of the structure significantly, while p+ d-doped layers ha...
