Abstract

Variations of friction force and surface potential were evaluated using friction force microscopy (FFM) and Kelvin force microscopy (KFM) on (100) and (001) faces of rutile single crystals under UV illumination in three different atmospheres: dry nitrogen, dry air, and ambient air. Friction force and surface roughness for the (100) face did not exhibit remarkable dependence on either UV illumination or on the atmosphere. However, the friction force of the (001) face increased by UV illumination in dry air without roughness variation. The surface potential of the (001) face changed negatively and more remarkably than that of the (100) face by UV illumination.
