摘要

Atomic force microscope (AFM), developed at Central Scientific Instrument Organization, Chandigarh, has been configured for load-depth indentation measurements, wherein 'the reverse path effect' of AFM force curve associated with the use of piezo actuators has been overcome by measuring in situ actuator displacement independently by a laser Doppler displacement meter (LDDM) to enable correction of the force curves. The measurements of elastic moduli of highly oriented pyrolytic graphite, silicone elastomer, mica and gallium arsenide have been carried out.
