Using solid-source MBE, strain-balanced quaternary AlGaInAs/AlGaInAs multiple quantum well (MQW) strucures have been grown and studied by photoluminescence (PL) and X-ray diffraction (XRD) measurements, showing high epitaxial quality and excellent ho

We have studied the electron spin resonance (ESR) at millimeterwave frequencies in high mobility AlGaAs/GaAs samples for the first time at filling factors v < 1 outside the v = 1 resistance minimum. The magnetic field dependence of the ESR measured a

We investigated the local potential distribution over gated double-bridge structures patterned on GaAs/GaAlAs heterostructures. The current and potential distribution over the gated double-bridge devices was measured for several sets of filling facto

We report on the realization of gain coupled distributed feedback (GC-DFB) lasers using masked implantation enhanced intermixing (MIEI) in a full planar technology. The process requires only planar epitaxy steps to minimize ion straggling. We present

The current- and temperature-dependent broadening of the resistivity peaks in the region between adjacent quantum Hall plateaus is measured in two different GaAs/AlxGa1-xAs samples. Power law behaviour is found for temperature and current scaling. Co

We have investigated the injection-locking (IL) technique as a useful tool to substantially reduce the chirp of directly modulated semiconductor lasers in standard fibre transmission systems. Chirpless transmission is presented for Fabry-Perot, bulk

In this paper we describe the analytical benefits of in situ preparation and imaging under inert and reactive media using an AlGaAs/GaAs superlattice structure as a well-defined model sample. Imaging under inert organic liquids like toluene has been
