An ultralow temperature scanning tunneling microscope (STM) was developed by installing an STM head in a dilution refrigerator. Using the apparatus, STM images and the differential tunneling conductance spectra were taken at the sample temperature of 90 mK on a cleaved surface of 2H-NbSe₂. The atomically-resolved and the CDW-modulated STM images, and the superconduting gap as well as the CDW gap in the tunneling conduction (dI/dV) spectra were observed. [DOI: 10.1380/ejssnt.2004.151]
