We propose a suitable explanation for Germanium Tin epitaxial heterostructures temperature-dependent photoluminescence that is based upon the so far disregarded optical activity of dislocations.
Warwick Physics seeks to make two academic appointments in the area of condensed matter physics (CMP). We specifically invite applications from candidates who work in the following areas: crystal growth, spectroscopy/modern optics, functional materials. At Warwick, the broad CMP research agenda spans traditional and emerging interdisciplinary areas, including diamond, ferroelectrics, magnetic materials, multiferroics, semiconductors, superconductors, and other novel functional materials.
Collaboration between the the Universidad Politecnica de Madrid, University of Birmingham and the Warwick XPS Facility has studied the evolution of surface chemistry and the associated wettability of laser-patterned aluminum alloys under abient conditions.
New results from the T2K experiment, in which Warwick is a key collaborator, have strengthened previous hints of a difference in the behaviour of neutrinos and antineutrinos . Neutrinos and antineutrinos come in three types (or flavours) and are capable of changing flavour as they travel from source to detector in a process known as 'flavour oscillations'. The recent analysis indicates that neutrinos and antineutrinos flavour oscillate with different probabilities. These results will help us shed light on the question of why the universe is dominated by matter, with very little observed antimatter.
