| الوصف: | We describe a multipurpose scanning tunneling microscope designed to operate in ultrahigh vacuum as well as in air, over a range extending from room temperature to liquid‐nitrogen temperatures. It is a single‐tube scanner design with a differential flexing approach mechanism mounted on a vibration isolation stack. The instrument features a novel in situ tip and sample exchange mechanism for extended operation under vacuum. A unique characteristic is that the vacuum chamber and all components with the exception of the gas‐cooled sample holder are at room temperature. We present preliminary data taken with this instrument, demonstrating atomic resolution constant current, constant height, and multiple‐bias imaging, gap‐modulated current‐voltage spectroscopy or simultaneous topography, and work function measurements, as well as lithography on the surfaces of graphite, Au(111) on mica, and GaAs(110). |
