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

The fabrication and performance of GaN-based micro-light emitting diode (-LED) arrays with 64 × 64 elements is reported. The diameter of each element is 20 m and center-to-center spacing 30 m, giving an overall active area of the arrays of 80425 m2. Through a novel fabrication approach including a isotropic dry etching and a self-aligned isolation technique, we could easily obtain an interconnection for a matrix-addressable array device. The arrays emit >50 W per element at 3 mA drive current. Adopting a spreading metal as a p-contact, the turn-on voltage was lowered down to 3.4 V.
