Open Access research with a real impact on health...

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 Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Structural and optical properties of MOVPE-grown GaInNAs quantum wells (QW) with multiple barriers (InGaAs/GaNAs) have been investigated. Significant improvement of optical performance in the 1.3 μm range is demonstrated with the proposed structure. PLE studies show that the density of N-related localized states can be reduced by the introduction of a thin InGaAs layer due to the improved interface quality. Based on the structural analysis, it is concluded that the InGaAs layer supports the nitrogen redistribution within the QW, resulting in a sharp interface. The blue-shift trend of the GaInNAs QW as a function of the GaNAs thickness can be explained by the reduction of the N content in the GaInNAs QW.
