p형과 n형 Si wafer의 111면위에 5x10-5mmHg의 진공내에서 SnO2-x박막을 Flash증착법으로 성장시킨 다음 산소분위기 속에서 열처리하여 Si-SnO2 heterojunction을 만들고 물성측정으로 부터 Energy bnad profile을 구하였다. 이 heterojunction은 양호한 정류성 Junction이며 400nm부터 1200nm까지 분광감도를 갖고 시정수가 -10-18sec로 고속광소자로 적합하며 Si p-n homojunction solar cell에 비하여 특성이 우수하고 제작이 간단하기 때문에 태양전지로 사용해도 손색이 없다. Si-SnO2 heterojunction was prepared by oxidzing at oxygen atmosphere SnO2-x Which made by Flith evaporation of SnO2 powder on III surface of p and n type Si single crystals. The energy band Profile of Si·SnO2 heterojunction was depicted from its physical properties. This heterojunction was very good rectifying junction, very sensitive in spectral response of Photovoltage at from 400nm to 1200nm, and -10-8sec of time contant. From above properties, this heterojunction was found ps good high speed photovoltaic device and solar cell.
