Abstract

We investigate the surface and interface engineering on InAs quantum dot (QD) emitters, by fabricating and measuring a series of edge-emitting light-emitting diodes. These diodes are encapsulated with non-stoichiometric silicon nitride (SiN) layers with various refractive indices. By analysing the o...
