摘要
The accumulation of adventitious carbon on Al and Au-Al alloy surfaces has been studied using XPS across a wide range of water vapour and air exposures. Carbon growth undergoes several discrete changes with the increase of exposure dose. X-ray irradiation effects on carbon growth were also investigated. Under x-ray irradiation Au-Al surfaces show a faster carbon growth than pure Al and Au metal surfaces. A fivefold increase of carbon contamination rate on an Au-rich Au-Al alloy (Au/Al = 5.0) surface has been observed. Copyright (C) 2002 John Wiley Sons, Ltd.
