摘要：

We present a simple design for a very-low temperature STM for the investigation of mesoscopic superconductors. The nonmagnetic microscope operates in a conventional He-3 cryostat at T = 240 mK and in magnetic fields up to B = 1 T. Efficient filtering of all electrical lines at base temperature results in a voltage resolution approximate to 20 mu V, which has been tested by measuring the differential conductance of superconducting aluminium. The successful operation in magnetic field is demonstrated by spectroscopy on superconducting aluminium as well as by demonstrating atomic resolution of HOPG.
