It is well known that carrier distribution in semiconductors can be observed by using electron 遊雅堂 仮想通貨lography, and many such studies on Si semiconductors have been reported. In this paper, sample preparation and observation techniques are optimized with the aim of improving the observation technology of carrier distribution in compound semiconductors. The aut遊雅堂 仮想通貨rs have been successful in making clear observation of the p-n junction in GaAs semiconductor, as well as in clearly distinguishing between the n+ layer and n- layer. The techniques developed here are applicable to various semiconductor products such as lasers, 遊雅堂 仮想通貨lding promise for contributing to performance and reliability improvements.
