To measure the reverse-bias voltage dependence of distribution of the photoacoustic signal from the depletion layer, the surface of the electrode was illuminated and scanned by an intensity-modulated optical-beam. It was obtained that the photoacoustic signal phase differences between depletion layer generating and non-depletion layer were dependent on the depletion layer spreading. One dimensional scanning on the electrode has also revealed that spreading of a depletion layer extends from the each edges of an electrode.本誌: 電気学会論文誌A（基礎・材料・共通部門誌） Vol.133 No.3 （2013） 特集：2011 International Symposium on Electrical Insulating Materials本誌掲載ページ: 127-131 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejfms/133/3/133_127/_article/-char/ja/
