A Compact 3D-nanopositioner of a scanning tunneling microscope operating at temperatures of 4.2-300.0 K

Résumé

A simple compact device for three-coordinate positioning of the tip of a scanning tunneling microscope, which is intended for operation in ultrahigh vacuum and a temperature range from room to helium (4.2 K) temperature. The nanopositioner contains two independent stepping piezoelectric motors. One of them is intended for bringing the tip to a sample (the Z axis) and the other, for positioning the tip in the sample plane (X, Y). The positioning accuracies at T = 4.2 K along the Z axis and in the plane of the sample (X, Y) are up to 10 and 40 nm, respectively. The maximum amplitudes of control pulses are +/- 250 and 140 V for the Z piezoelectric motor and the (X, Y) positioner, respectively (at 4.2 K). The device is manufactured from nonmagnetic materials and allows heating to 150A degrees C for operation in ultrahigh vacuum.
