We present the design and operation of a very low temperature scanning tunneling microscope (STM) working at 60 mK in a dilution refrigerator. The STM features both atomic resolution and micron-sized scanning range at low temperature. We achieved an efficient thermalization of the sample while maintaining a clean surface for STM imaging. Our spectroscopic data show unprecedented energy resolution. We present current-voltage characteristics and the deduced local density of states of hybrid superconductor-normal metal systems. This work is the first experimental realization of a local spectroscopy of mesoscopic structures at very low temperature. © 2001 American Institute of Physics. [ABSTRACT FROM AUTHOR] |
