Abstract

We investigated the growth of GaSb layers on Si (001) substrates by molecular beam epitaxy (MBE). Epilayers were grown as a function of Sb4/Ga beam equivalent pressure ratio (BEPR). They were then characterized by atomic force microscopy (AFM), X-ray diffraction (XRD), photoluminescence (PL), micro Raman scattering analysis. We confirmed that the optimum condition to grow relative high quality GaSb layer in this study was Sb4/Ga=20. (© 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
