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

The behavior of the E-2 and A(1)(LO) optical phonons in InxGa1-xN has been analyzed by Raman scattering over the whole composition range. The frequencies of the E-2 and A(1)(LO) modes decrease with increasing InN fraction. These modes display a significant broadening for an InN fraction of approximate to 60% and their linewidth decreases towards both ends of the composition range as a consequence of reduced cation disorder. Our results show a one-mode behavior for, both E-2 and A(1)(LO) modes of InGaN.
