We report direct measurements of the optical gain on vertical-cavity surface-emitting laser (VCSEL) material using a stripe-length method featuring segmented contacts. We utilise the similarity of the in-plane transverse electric (TE) polarised matri

Dilute nitrides based on GaAs constitute a family of compounds whose main characteristic is the band-gap tunability, depending on the nitrogen content. In this work we have focussed our attention on the indium free dilute nitrides, i.e. GaNAsSb with

Dust plays an important role in shaping a galaxy's spectral energy distribution (SED). It absorbs ultraviolet (UV) to near-infrared (NIR) radiation and re-emits this energy in the far-infrared (FIR). The FIR is essential to understand dust in galaxie

Aims: We compare the far-infrared to sub-millimetre dust emission properties measured in high Galactic latitude cirrus with those determined in a sample of 204 late-type DustPedia galaxies. The aim is to verify if it is appropriate to use Milky Way d

A GaInP/Ga(In)As/GaNAsSb/Ge 4-junction solar cell grown using combined MOVPE+MBE growth is used to analyze the effects during the integration of the subcell components into the full 4J structure. In this preliminary study, the Ge subcell is observed

Impact of annealing temperature, time and process gas on 1 eV GaNAsSb solar cells is assessed. In situ and ex situ annealings are carried out in order to analyze their effect on the solar cell performance. Ex situ annealings on as grown samples using
