摘要: 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 …
