Abstract
In this study we have grown epitaxial layers of wurtzite-CdS on CdTe((111) over bar)B/Si substrates using molecular beam epitaxy. Indium was used to o btain n-type doping of CdS. The concentration and uniformity of In was dete rmined by secondary ion mass spectrometry (SIMS). Indium profiles were obta ined for concentrations ranging from 5 x 10(17) to 1.4 x 10(21) cm(-3) and agree well with the variation expected from the In flux. (C) 2000 Elsevier Science B.V.
