초록
본 논문에서는 GaN 박막 위에 각각 알루미늄(Al)과 백금(Pt)을 증착하여 저항성 전극 및 투명한 schottky 전극을 형성한 평면형 자외선 수광소자를 제작하였다. 제작된 소자에 대해 전기적 특성과 광학적 특성을 조사하여 자외선 센서로서의 적합성을 검토하였다. 사파이어 기판위에 성장된 GaN 박막은
We fabricated a planar ultra-violet photodetector whose ohmic and schottky contacts were respectively formed with evaporated Al and Pt on the GaN layer. To examine the applicability of the device to the UV sensor, we investigated its electrical and optical characteristics. The GaN layer on the sapphire waver had
