Abstract

We describe the construction and operation of a novel scanning tunneling microscope, which is capable of operating throughout a wide range of pressures (atmospheric - 60 bar) and temperatures (300-650 K). The instrument has cylindrical symmetry and is constructed out of materials with low thermal conductivity and low coefficients of thermal expansion that allows imaging the same area over a wide temperature range. With this microscope we present images of the oxidation of polycrystalline nickel.
