Zusammenfassung:We have investigated the growth kinetics of Al oxide film by anodization in sulfuric acid solution and the electronic properties of this film using electrochemical impedance spectroscopy. Al oxide film consisted $Al_2O_3$ was grown based on the point defect model and shown the eclctronic properties of n-type semiconductor. 황산 용액에서 양극산화(anodization)에 의하여 생성되는 산화피막의 생성과정(growth kinetics)과 이 피막의 전기적 성질을 전기화학적 임피던스 측정법(electrochemical impedance spectroscopy)으로 조사하였다. 산화피막은 $Al_2O_3$로 점-결함 모형(point defect model)에 따라 성장하였으며, n-형 반도체의 전기적 성질을 보였다.
