Abstract:

We study the influence of the shell in InGaN nanowires with spontaneously formed core-shell structure on their optical and morphological properties. It is shown that removing the shell from the initial nanowires induces the  photoluminescence enhancement and changes their spectrum emission. Our research shows that etching the shell of these nanowires nanocrystals leads to their deviation from the vertical position.
