文摘

A thin layer of ZnO_0.3 deposited on a SiO₂ glass substrate was irradiated with a 2 MeV α microbeam. The disappearance of ZnO_0.3 in the neighbourhood of the beam was registered in situ. We quantitatively account for this behaviour in the framework of a very simple vaporisation model based both upon the local temperature increase resulting from the microbeam itself and upon the variation of the Zn vapour pressure with the local temperature. Other possible explanations are briefly discussed.
