Inspired by the possibility to boost the performance of future transistors and optoelectronic devices, we have explored the effect of strain in III-V nanowires. GaAs nanowires are characterized by a large yield strength and exceptional mechanical properties, making them an attractive system to study the enhancement of strain effects. At nanoscale dimensions, it is possible to achieve controllable growth of different crystal structures like zincblende or wurtzite, enabling new degrees of freedom to tailor electronic and optoelectonic properties. We show that the photoluminescence (PL) of zincbl...
