Abstract
MgO crystals have been studied by scanning-electron acoustic microscopy under different experimental conditions. Contrast mechanisms in imaging are discussed and compared. The experimental results obtained by earthing or nonearthing the specimen-transducer interface suggest the existence of a signal generation mechanism that is related to the ionic nature of these kind of crystals. Electron-acoustic microscopy appears then to be a useful tool for the characterization of ionic materials.This publication has 4 references indexed in Scilit:
