Introduction

​​Michele graduated with a BSc. from University College Cork (UCC) in 2011. She joined the MCAG group in 2012 under the supervision of Prof. Justin Holmes. She is co-supervised by Prof. Peter Parbrook based in Tyndall National Institute within the Nitrides Materials Group (NMG).

Her research is based on III-N materials focusing on Ultra-Violet light emitting diodes (UV LEDs) as an alternative to Hg based lamps. Using Metal Organic Vapour Epitaxy (MOVPE) she grows Multiple Quantum Well structures for LED production. In semiconductor materials crystal defects critically affect device performance. Using electron microscopy, atomic force microscopy and x-ray diffraction combined, a deeper understanding of how these defects are formed is achieved. Her research also involves methods to produce nanorods in III-N materials and use them to produce lower defect density templates for overgrowth of III-N devices. Novel self-assembled nano masks are made from block co-polymers and silica spheres for a top-down approach to produce nano-rods of various different diameters. Finally within her research, the impact of defects in device performance especially device assessing failure mechanisms is examined for III-N transistors and UV LEDs.​
