Abstract
Electron transport in nanostructured systems, with characteristic sizes that are less than the mean free path of the electron or the phase relaxation length of its wave functions, becomes so nontrivial that it requires reinterpretation and rephrasing of the term resistance itself. The examples of such systems are solid state realizations of electron Sinai billiards. An intriguing development in semiconductor “nanostructuring” technology has been nanostructure fabrication from suspended conducting semiconductor membranes detached from the bulk. Such structures, featuring a mutual coupling of electrical and mechanical degrees of freedom, are referred to as nanoelectromechanical systems. We describe the results of investigations into electron transport phenomena in semiconductor nanostructures, which also involve suspended nanostructures detached from the bulk.
