A novel scanning tunneling microscope (STM) is described which is constructed almost entirely of aluminum and uses bimorph piezoelectric disks as thex,y,zdrive elements. The design uses a simple, rugged tripod configuration for the fine motion drive arms. Coarse motion of the sample, which is mounted on an aluminum holder, is achieved by pushing or pulling, with a piezoelectric louse. Differential thermal expansion effects are avoided by design, to first order, and the resulting drift is ≤0.5 A˚/min after only a short warm‐up period. It is easy to build and operate, and has good immunity to mechanical vibrations. The frequency response is flat to 5 kHz. Thex,y,zdrive sensitivity is 8 A˚/V and the range is ≥12000 A˚. Some preliminary experimental results are presented, including atomic resolution images in air, of graphite and NbSe2.
