Cathodoluminescence hyperspectral imaging of nitride core-shell structures

Abstract

In this work, we demonstrate the use of hyperspectral CL in the evaluation of periodic arrays of GaN/InxGa1-xN core-shell nanorods. These were fabricated using a top-down approach, in which columns are formed from a GaN template using nano-imprint lithography and ICP etching, followed by MOCVD regrowth [2]. The formation of quantum wells (QWs) on the mplane sidewall facets offers a route to avoiding the detrimental electric fields associated with LEDs grown on the c-plane, while the use of periodic features has the potential to improve light extraction and directionality.
