Yamanaka, Kazushi and Ogiso, Hisato and Kolosov, Oleg (1994) Analysis of Subsurface Imaging and Effect of Contact Elasticity in the Ultrasonic Force Microscope. Japanese Journal of Applied Physics, 33 (5B). pp. 3197-3203. ISSN 0021-4922Full text not available from this repository.
We examined, both theoretically and experimentally, the characteristics of subsurface imaging with nanometer resolution and the effect of contact elasticity in the ultrasonic force microscope (UFM). In particular, the effect of the surface energy and effective elasticity on the maximum tip-sample force and the shift of the averaged tip-sample distance were examined. Furthermore, kink formation in the cantilever deflection (z(a)) against the ultrasonic frequency vibration (UFV) amplitude (a) characteristics was predicted. This model was used to explain experimental observations in UFM, such as the features of the measured z(a)(a) curve and the damping of the cantilever torsion vibration by the UFV. Moreover. the previously reported lateral ultrasonic force microscope image of subsurface features was explained by the response of subsurface edge dislocation to a large instantaneous force enhanced by the UFV.
