Scanning tunnelling microscopy in biotechnology
Trends in Biotechnology, 1990The scanning tunnelling microscope (STM) is capable of atomic resolution of highly conductive materials. Whether biological molecules can be visualized to the same extent remains an open question, but remarkable progress in the past year confirms the possibility of seeing the fine structure of nucleic acids, proteins, membranes and viruses, and ...

Scanning tunnelling microscopy of biomacromolecules
Journal of Microscopy, 1988SUMMARYWhen imaging biomacromolecules with a STM, coating of specimens with a conductive layer is a convenient preparation method which provides a good rate of success. Utilizing evaporated platinum/carbon as a coating film we have investigated two biomacromolecules of very different appearance.

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.
