Sj. Oshea et al., ATOMIC-FORCE MICROSCOPY STRESS SENSORS FOR STUDIES IN LIQUIDS, Journal of vacuum science & technology. B, Microelectronics and nanometer structures processing, measurement and phenomena, 14(2), 1996, pp. 1383-1385
Simple, sensitive, and fast sensors can be constructed from standard a
tomic force microscopy cantilevers. For use in liquid environments, it
is preferable to use changes in surface stress as the measurement bas
is of the sensor. We have constructed such a sensor in an electrochemi
cal cell so that simultaneous cyclic voltammograms and strain measurem
ents can be made. This is demonstrated with examples of underpotential
deposition of Pb on Au(lll) and electrocapillary effects in KCl. (C)
