TI - Chemical Vapor Epitaxy of Al$_{x}$Ga$_{1-x}$As CY - Amsterdam PB - Elsevier M1 - FZJ-2016-03308 SP - 1-6 PY - 2016 AB - A short overview about the growth chemistry of AlxGa1-xAs in the MOVPE process is given. Basic knowledge is necessary to understand the influence of growth parameters on GaAs and AlxGa1-xAs layer characteristics. Mainly the group III to group V partial pressure ratio and the growth temperature determine the quality of the bulk layers deposited. The optimal growth temperature window for AlxGa1-xAs is different in comparison to that for GaAs. A higher growth temperature is used if the AlxGa1-xAs quality is essential, and a lower temperature is used when the device structure requires abrupt interfaces.
