Nanometre scale monitoring of the quantum confined stark effect and emission efficiency droop in multiple GaN/AlN quantum disks in nanowires

Luiz Fernando Zagonel

University of Campinas – UNICAMP

Is a Professor at the Physics Institute of the Campinas University (Unicamp) in BRazil (São Paulo).  Has been working in instrumentation applied to the study of light emission by nano structures with high spatial resolution in the TEM and STM. Holds a PhD in Physics and worked as a Post Doc at the Université Paris Sud, France. 


We report on a detailed study of the intensity dependent optical properties of individual GaN/AlN Quantum Disks (QDisks) embedded into GaN nanowires (NW). The structural and optical properties of the QDisks were probed by high... [ view full abstract ]
