Xw. Yao et al., PIEZOELECTRIC SLIDING PUSHING MICROPOSITIONER IN A SCANNING TUNNELINGMICROSCOPE, Journal of vacuum science & technology. B, Microelectronics and nanometer structures processing, measurement and phenomena, 12(3), 1994, pp. 1646-1647
A piezoelectric micropositioner for coarse sample translation in a sca
nning tunneling microscope (STM) has been designed. The mechanical con
struction for the positioner is very simple, and it can be separated f
rom the sample carriage during STM imaging. The coarse sample movement
is obtained via a sliding-pushing mechanism, and a displacement speed
of 0.1 mm/s has been attained. The performance of the STM is tested b
y imaging a highly oriented pyrolytic graphite sample.
