摘要：

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 degrees C. Surface analysis has been performed by the RHEED and SEM techniques. A strong influence of electron transport anisotropy for HOPG has been observed. (C) 2009 Elsevier Ltd. All rights reserved.
