Summary

The sample holder is cooled by thermal conduction to the stage that thermally connects with the refrigerator head. The authors cleaved BSCCO single crystals under ultrahigh vacuum conditions, and measured tunnelling spectra of the bismuth-oxygen surface at 35 K. The spectra were smeared due to the fact that the scanning tunnelling microscope tip was at high temperature (higher than 100 K).
