Summary on Grant Application Form
The project is about various interesting phenomena that arise in electron tunnelling when the effects of interaction, disorder and multi-particle tunnelling are combined. To start with, the existence of a finite energy resolved current above the Fermi energy of a field emitter - the secondary current - is an experimental fact.This can only be explained as a joint effect of mutual electron-electron interactions inside the emitter and correlated tunnelling. The first challenge is to determine, by using the Keldysh non-equilibrium technique, the particular electron correlation function responsible for this process in a given experimental set-up, e.g. when the tunnelling occures from a microscoric (tip) or macroscopic area of the emitter's surface. The relevant correlation functions will then have to the analysed, using a variety of theoretical methods, for different emittors. The primary application here, of a potential technological value, is to multi-wall Carbon nanotubes. Both in the field emission and in the conventional non-equilibrium contact set-ups, the backflow of holes exites the interacting emitter and creates a continuum of electron-hole pairs around the Fermi energy. These pairs can photorecombine, the intensity of which process is to be theoretically investigated. Applications are again to Carbon nanotubes. At the later stage of the project, it is planned to theoretically study the non-equilibrium tunnelling of electrons through individual molecules and longer molecular wires that can elastically deform accommodating the applied bias voltage.
