摘要: 本文用DLTS譜儀研究了SiO2限制的InGaAsP/InP雙異質(zhì)結(jié)發(fā)光管中的深能級(jí)。結(jié)果表明:只有在p-n結(jié)位于p-InP/n-InGaAsP界面處的個(gè)別器件中,有△E=0.24eV的多子陷阱。Abstract: The deep level in InGaAsP/InP DH LED have been studied by DLTS method. The results show that when the p-n junction located in the interface of the p-InP/n-In GaAsP, there is deep level in some InGaAsP/InP DH LED. The activation energy △E is 0.24eV.
