We have performed a quartz crystal microbalance (QCM) experiment for Kr films adsorbed on a single-crystalline graphite substrate at various temperatures. The substrate enables us to study the oscillation direction dependence of the sliding friction. In the present experiment, the direction is parallel to the a-axis of graphite. It was found that the resonance frequency at 85 K does not change greatly until the film enters the commensurate phase. At the commensurate phase, the resonance frequency starts to decrease. In addition, at the transition from the commensurate phase to the incommensurate phase, the coverage dependence of frequency changes slightly.
