英文摘要Interaction of hexagonal boron nitride (h-BN) with gases is of great importance for its properties and applications. In the present work, the structural changes of h-BN overlayers on Pt(111) in oxidative atmospheres including O-2 and NO2 have been investigated by using low energy electron microscopy, Auger electron spectroscopy, X-ray photoelectron spectroscopy (XPS), and near ambient pressure XPS. We find that h-BN islands can be intercalated by oxygen in 10(-6) Torr O-2 at 200 degrees C, while oxygen intercalation of full layer h-BN around 200 degrees C requires near ambient pressure O-2 (0.1 Torr) or such a strong oxidant as NO2 (10(-6) Torr). h-BN overlayers can be etched away in the gases at much high temperatures, e.g. 800 degrees C. Upon mild oxidation in O-2 or NO2 at temperatures of 400-450 degrees C, h-BN is transformed to boron oxide (BOx) overlayers, which can be converted back to h-BN by heating in NH3 at 800 degrees C.
