High efficiency compound semiconductor concentrator photovoltaics [PDF]

Special emphasis was given to the high yield pilot production of packaged AlGaAs/GaAs concentrator solar cells, using organometallic VPE for materials growth, the demonstration of a concentrator module using 12 of these cells which achieved 16.4 percent ...

AlGaAs Tunnel Junction (TJ)-VCSELs: A NEGF–Drift-Diffusion Approach

IEEE Photonics Journal
This work reports a multiscale physics-based approach aimed at investigating the benefits of introducing a single tunnel junction (TJ) within conventional AlGaAs Vertical-Cavity Surface-Emitting Lasers (VCSELs).

Temperature and electron density dependence of spin relaxation in GaAs/AlGaAs quantum well

Nanoscale Research Letters, 2011
Temperature and carrier density-dependent spin dynamics for GaAs/AlGaAs quantum wells (QWs) with different structural symmetries have been studied by using time-resolved Kerr rotation technique.

THE EFFECT OF ELASTIC STRESS ON THE PROCESS OF OBTAINING InGaAs/AlGaAs QUANTUM WELL BY MOCVD

Тонкие химические технологии, 2013
Strained InGaAs/AlGaAs quantum wells based on GaAs substrates are successfully used in wide optoelectronic applications. In this paper the advantages of these strained wells and their manufacturing difficulties in MOCVD have been described.
