Abstract

original image

The properties of high-quality InN nanobelts fabricated by the metal-organic chemical vapor deposition technique are investigated. The figure shows the uniaxial strain ϵ3 (, solid squares) and in-plane strain ϵ1 (solid circles) as a function of excitation intensity. The reduction of the tensile in-plane strain gives rise to a noticeable increase of the band gap energy.
