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

Spontaneously formed nano-pits are exploited to effectively control the incorporation of gold nanocrystals (NCs) at the surface of light emitting InGaN/GaN heterostructures. Nano- engineering either the NCs size, or pit size, allows the number of NCs incorporated in each pit to be controlled, thus enabling research of well-defined assemblies of few gold NCs using an optically and electrically active substrate (see figure). The development of new nano-devices based on such hybrid nanostructures is briefly discussed.
