ABSTRACT
The uninterrupted growth of high quality GaInAs layers on InP buffers by atmospheric pressure metalorganic chemical vapor deposition using trimethylindium is reported. A lattice mismatch smaller than 4.3×10-4 and low-temperature photoluminescence exciton linewidth of 2.6 meV have been obtained, along with best 300-K, 77-K, and 4.2-K Hall mobilities of 11 200, 64 000, and 80 000 cm2/Vs, respectively. Such high mobility values at 4.2 K are explained by the existence of a two-dimensional electron gas and demonstrate the superior quality of the GaInAs epilayers grown in our laboratory.
