A thermally compensated tube scanner scanning tunneling microscope utilizes two concentric piezoelectric tubes, one for scanning and one for coarse translation as well as fine adjustment of sample position while in tunneling range. There are no mechanical components such as springs, levers, gears, or stepper motors which are known to result in considerable vibration sensitivity and thermal drift. Consequently, the standard mode of atomic resolution operation for the device is without vibration isolation and with a thermal drift of less than 1 angstrom per hour.
