摘要： A method of operating a scanning probe microscope includes using a probe having a cantilever, and oscillating the probe at a torsional resonance frequency thereof. In addition, the method includes substantially increasing torsional drive efficiency with dual actuators disposed on the probe or the probe base. First and second actuators may be driven by corresponding first and second drive signals, the first and second drive signals being about 180° out of phase. The maximizing step includes altering at least one of the amplitudes of the first and second drive signals to maximize torsional oscillation. Torsional and flexural oscillation of the cantilever probe can be excited concurrently, sequentially or independently by adjusting the phase of the corresponding drive signals. A pair of cantilever components can be used to form a nanotweezer by rotating the respective arms having corresponding tip portions at the distal ends.

摘要： A drive actuator for a measurement instrument having a probe, the drive actuator including a heating element in a thermally conductive relationship with the probe such that application of electric current to the heating element modifies a characteristic of the probe. The probe device includes a probe including a cantilever having a lever made of a material having a selected thermal expansivity and a drive actuator in operable cooperation with the cantilever lever made of a material having a thermal expansivity different than the thermal expansivity of the material of which the cantilever lever is made.
