一种Cu-9at.%的合金Al（111）在低能电子衍射（LEED）/AES和扫描AES仪器中在高温下被氧化。在995 K下加入1300 L氧气，在Cu-9at.%铝合金。经LEED证实的有序氧化物的结构为（$7/\sqrt{3} \times 7/\sqrt{3}$）R30°。氧化物的化学状态为Al 2 O3。在扫描AES仪器中用SEM观察到的表面的形态揭示了具有相同取向的三角形缺陷的平坦的氧化物生长。讨论了合金衬底与氧化铝层之间可能的外延生长。版权所有© 2003年约翰威利父子有限公司。
An alloy of Cu–9at.%Al(111) has been oxidized in a low‐energy electron diffraction (LEED)/AES and a scanning AES instrument at elevated temperatures. Dosing with 1300 L of oxygen at 995 K gives rise to well‐ordered oxide layer formation on the Cu–9at.%Al alloy. The structure of the ordered oxide confirmed by LEED is ($7/\sqrt{3} \times 7/\sqrt{3}$) R30°. The chemical state of the oxide was Al2O3. The morphology of the surface observed with SEM in the scanning AES instrument revealed flat oxide growth with triangular defects of the same orientation. The possible epitaxy between the alloy substrate and alumina layer has been discussed. Copyright © 2003 John Wiley & Sons, Ltd.
