摘要
The paper reports surface modification of SiC by Ar+ ion sputtering. Observations were performed with an ultra high vacuum atomic force microscope operating in the contact mode. The surface morphology and topography were investigated with simultaneous measurement of local changes in electric conductance. We show that the Ar+ ion bombardment of the 6H-SiC wafer surface affects the surface stoichiometry, changing the character of a metal/SiC contact from the Schottky barrier diode type into an ohmic contact type.
