Abstract

CuPt-type ordering has been observed in Zn-rich $Cd_xZn_{1-x}$Te epilayers grown on (001)GaAs and ZnTe/GaAs(001) substrates. X-ray diffraction, electron beam diffraction, high-resolution transmission electron microscopy and low-temperature photoluminescence have been used to characterize the CuPt-type ordering in Zn-rich $Cd_xZn_{1-x}$Te epilayers.

GaAs (001) 기판과 완충층을 사용한 ZnTe/GaAs(001) 기판 위에 고농도의 Zn 조성을 가지는 $Cd_xZn_{1-x}$Te/GaAs, $Cd_xZn_{1-x}$Te/ZnTe/GaAs 에피층 구조를 성장시켰다. 이때 $Cd_xZn_{1-x}$Te 에피층에서의 CuPt형의 규칙상 형성, 미세구조적 특성과 광발광특성을 X-선회절과 전자회절상, 고분해능 투과전자현미경, 그리고 저온 광발광 측정 장치를 이용하여 연구하였다.
