Development of a scanning tunneling microscope for in situ experiments with a synchrotron radiation hard-X-ray microbeam.

A scanning tunneling microscope dedicated to in situ experiments under the irradiation of highly brilliant hard-X-rays of synchrotron radiation has been developed. In situ scanning tunneling microscopy (STM) observation was enabled by developing an accurate alignment system in ultrahigh vacuum. Despite the noisy conditions of the synchrotron radiation facility and the radiation load around the ...

Simulating Scanning Tunneling Microscope

Design considerations and performance of a combined scanning tunneling and scanning electron microscope

We designed and built a combination of a scanning tunneling microscope ~STM! and a scanning electron microscope ~SEM! which is working under ultrahigh vacuum conditions ~base pressure typically 7 • 10 mbar!. The SEM is ideally used for surveying the sample and to control the STM tip positioning, while the STM extends the resolution range into the atomic scale. The design concept allows moving t...

A Walking, Scanning Tunneling Microscope Combined with a Focused Ion Beam

A walking, concentric-tube STM has been designed to interface with an F a . The outer tube, which stands upright on 3 spherical feet, supports the inner tube and serves as an inertial stepper, allowing the STM to move laterally relative to a sample. The ion beam can pass down through the center of the inner tube, which operates as a conventional tube scanner with the STM tip at its lower end. T...
