Abstract
An apparatus using a resonator probe for determining an electronic property of a conductor across a dielectric. The apparatus has a device for inducing lateral mechanical oscillations of the resonator probe and a voltage source for producing a voltage difference between the resonator probe and the conductor to create an electronic drag between the conductor and resonator probe, thus damping the mechanical oscillations of the probe. The electronic property, such as charge carrier mobility, surface resistance, charge carrier lifetime and the number of charge carriers is determined from the damping experienced by the probe.
