Taper-Free Faceting in GaAs Nanowires for Improved Optoelectronic Properties
An infographic highlighting taper-free faceting as a method to gain ultralow-surface recombination velocity in nanowires
We would like to share an infographic highlighting the excellent work by Zahra Azimi, Jennifer Wong-Leung et al. on taper-free faceting in GaAs nanowires which gives the lowest surface recombination velocity reported for GaAs nanowires, despite the presence of twin defects! Check out the infographic below to learn more or get the full story from their Nanoscale Horizons article.

Zahra Azimi
Zahra Azimi is currently a PhD candidate in the Research School of Physics at the Australian National University. She received her BSc and MSc in Materials at Sharif University of Technology. Prior to starting her PhD, she worked as an R&D in a nanotechnology company with focus of self-cleaning and multi-functional coatings. Her research interests are epitaxial growth of III-V materials and characterisation and analysis of semiconductor nanostructures. Her PhD research focuses on the growth of InGaAs nanowires by selective area metal organic vapour phase epitaxy for optoelectronic applications |
