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 ...
It was pioneered by Gerd Binnig and Heinrich Rohrer in 1982, and was awarded a Nobel Prize in Physics in 1986.Typical STM experimental setup consists of a sharp metallic tip which is brought within ...
