Popis: | GaAs (001) surface ultrasonically cleaned under running de‐ionized water (U‐RDIW) is investigated by reflection high‐energy electron diffraction (RHEED). The RHEED observations of U‐RDIW‐treated surfaces show a spotty (1×1) pattern at room temperature and a (2×1) streaky surface reconstruction pattern at 360 °C. The experimental results indicate that chemically clean and damage‐free GaAs surfaces can be produced by U‐RDIW treatment. We discuss surface structures before/after heating using a hydrogen‐ terminated model. |
