AbstractWe theoretically and numerically demonstrate that the spontaneous parity-time (PT) symmetry breaking phase transition can be realized respectively by using two independent tuning ways in a tri-layered metamaterial that consists of periodic array of metal-semiconductor Schottky junctions. The existence conditions of PT symmetry and its phase transition are obtained by using a theoretical model based on the coupled mode theory. A hot-electron photodetection based on the same tri-layered metamaterial is proposed, which can directly show the spontaneous PT symmetry breaking phase transition in photocurrent and possesses dynamical tunability and switchability. This work extends the concept of PT symmetry into the hot-electron photodetection, enriches the functionality of the metamaterial and the hot-electron device, and has varieties of potential and important applications in optoelectronics, photodetection, photovoltaics, and photocatalytics.

Analytical solutions of a Dirac-type equation as effective mass equation. for electrons are obtained and by means of these solutions we have analytically calculated the relativistic transmission coefficient for quantum electron ballistic tunneling through Ga 1−x Al x As -GaAs single barriers. This solution for the transmission coefficient is applied to the tunnel injector of a hot electron device finding that relativistic corrections yield small but significant shifts in the transmittance-voltage characteristics.

ABSTRACTThe multiple-scan method of electron beam annealing has been used to activate shallow (Rp<150Å), highly doped silicon layers produced by ion implantation of arsenic at 10keV. Beam conditions have been optimised (600Wcm−2 for 100ms) to produce essentially undiffused layers, as determined by high resolution SIMS, containing high concentrations of electrically active arsenic impurities. Computer modelling of diffusion effects in such layers has been used to identify optimum beam conditions and the calculations have been compared with experimental results. Hot electron device structures, which depend on negligible diffusion and high electrical activity, have been fabricated using the multiplescan method with a peak annealing temperature of 900°C.
