摘要: 我们对N-GaAs和N-InP单晶及外延层在4.2K和77K下测定了光致发光谱,并用C-V法测定了电学参数,确定了未掺GaAs中的受主杂质主要是C和Si.通过室温离子注入Si和退火处理,证明了GaAs中1.403eV光谱峰与Si及砷空位VAs有关,结合化学及离子微探针分析结果,对未掺InP晶体光谱曲线研究指出,~1.38eV光谱峰是C受主引起的,而1.08和~1.2eV峰分别与磷空位Vp及铟空位VIn有关.

Abstract: In this paper, the photoluminescence spectra of n-GaAs and n-InP single crystals as well as epitaxial n-InP have been investigated. The electrical properties were measured by means of c-v. It was determined that the residual acceptor impurities are dominantly C and Si in the undoped GaAs. By ion implantation with Si at room temperature, followed by annealing treatment, it has been proved that the 1.403eV peak of the spectrum in GaAa is related with Si and VAs. Incorporated with the results of the chemical analysis as well as the ion probe, the investigation of the spectra for the undoped n-InP crystals shows that the -1.38eV peak of the spectrum is caused by C acceptor; 1.08 and -1.2eV speaks are connected with VP and VIn respectively.
