    • Abstract

       

      It was shown earlier that during quantum mechanical tunnelling, a microscopic particle has a distributed probability of emission about its original energy and is not constrained to be field-emitted only at its initial energy. Such an energy distribution process appears obvious on the quantum theory of observation and measurement which relates the energy of a microscopic particle with the time required for its determination through the Heisenberg’s uncertainty relation. Here, an account of the tunnelling theory based upon the latter is presented. The consequent analysis gives rise to a spectrum in the energy of the transmitted electrons and also yields a method to estimate the tunnelling time as well as the tunnelling current density across an arbitrary barrier.
