Theory of scanning tunneling microscopy
Applied Physics A Solids and Surfaces, 1990The present theoretical understanding of imaging clean and adsorbate covered metal surfaces in scanning tunneling microscopy is examined with special emphasis on a possible theoretical foundation for the observed unexpectedly large corrugation on close-packed metal surfaces.

Abstract : Scanning tunneling microscopy (STM) has been used to image and modify the surfaces of III-V, II-VI and group IV semiconductors. A tip-simulator based on a photocode was developed. The simulator allows the development of ultra- sensitive electronics for controlling STM tip movement.

Scanning tunnelling microscopy
Contemporary Physics, 1991Abstract Since its inception in 1982, the Scanning Tunnelling Microscope (STM) has had an increasing importance in the examination of surfaces at an atomic level in real space. The unique performance of this imaging technique stems from the quantum tunnelling process employed.

Scanning tunnelling microscopy
Vacuum, 1994Scanning tunnolling microscop! (STM) is a rclativcly new tccbnique. originating as it does from pioneering work of Binnig and Rohrcr in the early 1980s ‘. The concept is relatively simple. J~tst place ;I slurp tungsten tip close to a conducting surl~lcc. so close that the W:ILC‘ functions of the closest tip atom and the surface atoms overlap.

STM is a surface microscope with extremely high spatial resolution, which enables us to see atoms on surfaces. When a sharp metal needle is located at a very proximate distance (~1 nm) from the sample surface (left panel in Fig. 97.1), tiny amount of electrical flow, called a tunneling current, is induced between them. Since the current is so sensitive

Scanning Tunnelling Microscopy
1992The scanning tunnelling microscope, or STM, has emerged over the last few years as a fascinating new technique for examining conducting solid surfaces with high resolution [10.1–5]. A sharpened metal wire is brought close enough to the surface so that the electrons “tunnel” across the narrow gap (0.5–1.5 nm).
