Abstract:In this work it was demonstrated theorstically and experimentally that the chloride VPE technique is available for the GaAs/Si heteroepitaxy. The surface of the GaAs/Si layers is flat and bright.The composition measurements X-ray deffraction analysis of the layers and HRTEM observion of the GaAs/Si interface were performed. The results indicate that the GaAs/Si layers are single crystal with GaAs stoichiormetry. The carrier concentration of GaAs/Si layers can be controlled in the range of 1014-1017 cm-3 with a flat longitudinal concentration profile. The GaAs/Si MESFETs with transconductances of 40mS/mm have been fabricated.
