Open Access research with a European policy impact...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

Abstract

Three series of 1 mu m thick Ga1-xMnxAs films with different Mn composition have been characterized using high-resolution x-ray diffraction (HRXRD). The results show that they are highly-crystalline and the growth is reproducible. The Mn compositions have also been measured by other popular methods: in situ ion gauge, x-ray fluorescence (XRF), electron probe microanalysis (EPMA) and secondary ion mass spectrometry (SIMS). The results show that the Mn concentrations measured by different methods are different and the difference between them becomes smaller with increasing Mn content.
