The first demonstration of a one-step-growth vertical-cavity surface-emitting laser (VCSEL) at 1.56 /spl mu/m by low-pressure metal-organic vapor phase epitaxy in the InGaAlAs (/spl lambda//subâ€¦ (More)

This paper deals with transport properties at low applied electric field in a one-dimensional semiconductor superlattice. Two scattering processes are considered : deformation potential and polarâ€¦ (More)

2014 The near equilibrium mobility tensor in a one-dimensional superlattice is studied. Analytical formulae are given for acoustical phonon scattering. Discussion of the results shows that the kâ€¦ (More)

Two different algorithms have been developed for calculating one-dimensional self-consistent numerical solutions to the Schrodinger and Poisson equations for electron states in III-V multi-layerâ€¦ (More)

AlInAs/GaInAs Metal-Semiconductor-Metal photodiodes have been fabricated by MBE. The structure incorporates an AlGaInAs graded region to avoid photocarrier trapping and to provide surfaceâ€¦ (More)

We report on millimetre-wave superlattice oscillators intended for use in optically-fed wireless communication systems as injection locked light to mm-wave converters. mm-wave generation isâ€¦ (More)
