A self-consistent numerical calculation is made of the potential profile in an accumulation layer with single subband in the lightly n-doped emitter contact of a vertical tunnel structure under an applied bias. A background of fixed minority acceptor

The concept of tunnelling is almost as old as quantum mechanics itself. Oppenheimer (1928) wrote a paper on a hydrogen atom in an electric field as early as 1927. He calculated the rate of dissociation of the hydrogen atom and developed a method for

This chapter examines some important properties of single and double barrier tunnelling heterostructures. Particular emphasis is placed on the use of magnetic fields in studying not only the tunnelling process itself, but also the way in which electr

Fromhold et al. reply — Unstable but periodic classical orbits are of fundamental importance in quantum chaology6,7. They produce regular clustering of the energy levels6 and certain states exhibit regions of enhanced probability density or ‘scar

In any course of quantum mechanics it is necessary to explain the behaviour of incompatible dynamical variables when measurements are made of them and also the noncommutation of their corresponding operators. At the outset this presents the student w

The thermal conductivity of 3He-4He mixtures is calculated in the temperature range 50 mK to 500 mK allowing for the presence of three-phonon processes. By comparing the theory with experiment, the authors are able for the first time to obtain inform

Measurements of the linear coefficient of thermal expansion of UO 2 from 1.5 to 35 K show a first-order magnetic transition atT N=30.36 K (single crystal) and 30.40 K (sintered compact) with an associated strain Δl/l ≅ 25×10 −6 . Comparison of
