    Hot-Electron Spectroscopy and Transistor Design

    The generation of hot electrons and their relaxation over short distances has been investigated in multilayer semiconductor structures. Scattering due to electron-electron interactions has been identified as t...

    Aspects of 2D And 3D Conduction in Doped Semiconductors

    In this article we present some recent results on conduction in doped semiconductors. There are two topics considered here. The first is the use of the GaAs MESFET (Schottky gated FET) as a system for the inve...

    Length Scales and the Quantised Hall Effect

    We have extended earlier measurements on the frequency dependence of the quantised Hall resistance in Silicon inversion layers to higher frequencies and magnetic fields. The frequencies reduce the transport le...

    Macroscopic quantum electrodynamic effects in a superconducting ring containing a Josephson weak link

    The problem of coherent flux tunnelling across a Josephson weak link enclosed by a thick superconducting (‘SQUID‘) ring in terms of quantum electrodynamics is considered. We show that for a low effective noise...
