Imaging doubled shot noise in a Josephson scanning tunneling microscope

Nettet11. okt. 2024 · The STM doesn’t work the way a conventional microscope does, using optics to magnify a sample. Instead a sharp (1-10 nm) probe that is electrically conductive is scanned just above the surface of an electrically conductive sample. The principle of STM is based on tunneling of electrons between this conductive sharp probe and sample. Nettet10. des. 2014 · We have studied the superconducting Si(111)−(√7×√3)−In surface using a 3He -based low-temperature scanning tunneling microscope.
