Abstract

The correlation between the temperature dependences of ion-induced electron emission yield, modified surface crystalline structure and morphology of isotropic graphite MPG-8 and highly oriented pyrolytic graphite (HOPG) UPV-1T under high-fluence ( F = 10 18–10 19 ion/cm 2) 6–30 keV Ar + ion irradiation has been studied and discussed. The target temperature has been varied during continuous irradiation from room temperature to 400 °C. Surface analysis has been performed by the RHEED and SEM techniques. A strong influence of electron transport anisotropy for HOPG has been observed.
