Combined Scanning Tunneling Microscope and Quartz Microbalance Study of Molecularly Thin Water Layers
A combined quartz crystal microbalance and scanning tunneling microscope has been used to monitor frictional drag forces on the microbalance, which are due to the presence of the microscope’s scan tip. The experiments have been carried out with varying thicknesses of water adsorbed on the surface of the microbalance. Increased friction between the tip and the substrate is observed at moderate film thicknesses.
