摘要

The effects of temperature and electron energy on the electron-irradiation-induced decomposition of sapphire have been investigated by in situ transmission electron microscopy (TEM). It was found that the decomposition rate of α-Al2O3 increased with increasing irradiation temperature and decreased with increasing acceleration voltage. The core-hole Auger decay process (K-F model), rather than knock-on displacement, is responsible for the decomposition of α-Al2O3 under electron irradiation.View full textDownload full textKeywordsalumina, electron irradiation, phase transformations, transmission electron microscopyRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/09500839.2010.501768
