Variable Temperature Omicron STM

In Scanning Tunneling Microscopy (STM) a very sharp tip is moved close to the sample and a small voltage is applied across the two. This causes electrons to tunnel through the vacuum between the two electrodes. The tunneling current depends exponentially upon the height of the tip above the sample giving the STM atomic resolution.
