13 mai 1981 - The Topografiner and STM
Description:
The Topografiner was invented by Russell Young and his colleagues Gerd Binnig and Heinrich Rohrer
This microscope works on the principle that the left and right piezo (electric charge that wonders in certain solids) drivers scan the tip over and slightly above the specimen surface. The center piezo is controlled by a servo system ( Servomechanism) to maintain a constant voltage. This results in a consistent vertical separation between the tip and the surface.
The scanning tunneling microscope (STM) is a type of electron microscope that shows 3D images of a sample. In the STM, the structure of a surface is studied using a stylus that scans the surface at a fixed distance from it.
The two people in the photo are Gerd & Heinrich and the machine is the ''Scanning Tunneling Microscope".
