Scanning tunneling microscope Řádkovací tunelový mikroskop

• 1981 G. Binning, H. Rohrer

• 1986 NP physics

• Tunneling current – electrons in small vicinity over sample surface – when approached by tip ended by single atom.

• Current changes with distance of tip from sample.

• With combination of XY piezoscanner we can obtain topographic image

• Conducting and SC surfaces
