Quantum Size Effect Due to the Electron Transport over Bismuth Nanobridges with 2D Electron Gas

Quantum Size Effect Due to the Electron Transport over Bismuth Nanobridges with 2D Electron Gas A quantum size effect due to the electron transport over nanobridges made from 40-nm-thick polycrystalline Bi films with an average grain size equal to the nanobridge length is discovered and investigated experimentally. It consists in the oscillations of resistivity as a function of nanobridge width. It is found that the magnitude of oscillations is proportional to h/2e 2 and their period is 50 nm. These imply a mean de Broglie wavelength of 100 nm for conduction electrons. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Microelectronics Springer Journals

Abstract

A quantum size effect due to the electron transport over nanobridges made from 40-nm-thick polycrystalline Bi films with an average grain size equal to the nanobridge length is discovered and investigated experimentally. It consists in the oscillations of resistivity as a function of nanobridge width. It is found that the magnitude of oscillations is proportional to h/2e 2 and their period is 50 nm. These imply a mean de Broglie wavelength of 100 nm for conduction electrons.
