WebJun 4, 1998 · We have placed a scanning tunneling microscope (STM) in the sample stage of a scanning electron microscope (SEM). This allows us to focus the tip on a preselected spot for STM operation with a precision of 0.5 μm. We are able to check the state of the sample and the tip during STM operation by simultaneous use of the SEM. We are also … WebFigure 21.3. 1: Schematic diagram of an instrument for scanning electron microscopy, which consists of an electron gun, a system of magnetic lenses, a scan control, and a detector. …
