Geは次世代電子デバイス材料として注目され、その酸化研究は重要となっている。本発表では、酸素分子のGe(100)-2$$times$$1表面への室温初期吸着確率の並進エネルギー依存性を報告する。0.1eVと0.47eV付近に酸素分子の吸着バリアーの存在を示唆する結果を得た。

Ge and its oxidation are attracting widespread interest in the field of development of future electronic devices. In this conference, we report incident energy dependence of initial sticking probability for a Ge(100)-2$$times$$1 surface at room temperature. We obtained results which suggest two energy barriers for O$$_{2}$$ adsorption at around 0.1eV and 0.47 eV.
