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

We have employed high resolution electron energy loss spectroscopy (HREELS) (in ultrahigh vacuum) to investigate the band gap of the novel semiconductor BC2N by measuring electronic excitations from the valence band to the conduction band. Angle-resolved HREELS allows the observation of transitions which are not vertical in k space, and the measurements indicate an indirect band structure, even though this material emits visible photoluminescence. The results also reconcile scanning tunneling microscopy and photoluminescence measurements for the system.
