Scanning Tunneling Microscopy: A tool for Studing Self-Assembly and Model Systems for Molecular Devices (AN85)

From Veeco Instruments
 

 

The invention of the scanning tunneling microscope in 1982 initiated the creation of what is known today as a whole family of scanning probe microscopies (SPMs). The importance of scanning tunneling microscopy (STM) was soon recognized and culminated in the award of half the 1986 Nobel Prize in Physics to Binnig and Rohrer. Early STM work focused mainly on the clean, bare surfaces that exist under ultrahigh vacuum (UHV) conditions and provide ideal systems for formulating and testing theories of tip-sample interactions and electron transport. A great expansion of STM research was started in 1986, when
Digital Instruments introduced the first commercial scanning tunneling microscope operating in ambient conditions, the NanoScope STM.

The ability to perform STM work in air, under solutions, and within electrochemical cells has made the interrogation of self-assembly practical. The high resolution achieved with relative ease in STM images sets this technique apart from other SPMs and has allowed numerous STM studies to address the structure and dynamics of self-assembled monolayers in exquisite detail. Two-dimensional self-assembly on surfaces and at interfaces is often cited as an important ingredient for any
