Hot-wall epitaxy법으로 GaAs 기판 위에 성장시킨 CdTe 박막은 (III) 면의 단결정 박막으로 성장되었음을 XRD 측정으로부터 확인하였으며, 박막 성장률은 SEM 측정 사진으로부터 30 $AA/s$임을 알았다. PL 측정으로 얻은 최적성장조건은 원료물질 온도 $500^{circ}C$, 기판 온도 $320^{circ}C$이었다.
CdTe thin films were grown on GaAs (100) substrates by hot wall epitaxy method. From the XRD measurements, it was found that CdTe/GaAs (100) film was grown as a single crystals with the different from growth plane of (III), and growth rate of CdTe thin films was found to be 30 $AA/sec$ by SEM. To acquire a high quality CdTe thin film, the optimum temperature for the source and substrate are found to be $500^{circ}C$ and $320^{circ}C$, respectively, which was checked by PL.
