In most conventional STM studies, tip consists of W or PtIr alloy which has a flat density of states around Fermi level (this is confirmed during the process of high-bias field-emission on a Au or ...

For maximum resolution in a scanning tunneling microscope (STM), an extremely sharp metallic tip is required, which serves as the point through which the STM “scans” a sample. A blunt tip reduces STM ...

No. 3 seeded STM will take on No. 4 seed St. Augustine after both squads won their semifinal matchups by a two-point margin, and Saturday's matchup started off as a nail-biter as well. The Cougars ...
