Inelastic Electron Tunneling Spectroscopy
... Inelastic electron tunneling spectroscopy (IETS) is an experimental tool for studying the vibrations of molecular adsorbates on metal oxides ... Some of the tunneling electrons can lose energy by exciting vibrations of the oxide or the adsorbate ... These inelastic processes lead to a second tunneling path, which gives an additional current contribution to the tunneling current ...
Scanning Tunneling Spectroscopy - Tunneling Current

Famous quotes containing the words current and/or tunneling:

    Gradually the village murmur subsided, and we seemed to be embarked on the placid current of our dreams, floating from past to future as silently as one awakes to fresh morning or evening thoughts.
    Henry David Thoreau (1817–1862)

    Our major universities are now stuck with an army of pedestrian, toadying careerists, Fifties types who wave around Sixties banners to conceal their record of ruthless, beaverlike tunneling to the top.
    Camille Paglia (b. 1947)
