How much better are InGaN/GaN nanodisks than quantum wells - oscillator strength enhancement and changes in optical properties

Lei Zhang, Leung-Kway Lee, Chu-Hsiang Teng +3

We show over 100-fold enhancement of the exciton oscillator strength as the diameter of an InGaN nanodisk in a GaN nanopillar is reduced from a few micrometers to less than 40 nm,…
