Abstract

A light article includes: a substrate; a truncated cuboidal fin disposed on the substrate and including: a laterally-grown nanocrystal including a longitudinal length and a lateral length that are different; a charge injection facet arranged along a longitudinal fin axis of the truncated cuboidal fin; and a truncation facet disposed opposing the charge injection facet and arranged parallel to the longitudinal fin axis; a side-injector disposed on the charge injection facet of the truncated cuboidal fin and that provides electrons to an active layer; and the active layer interposed between the side-injector and the substrate and that: receives electrons from the side-injector; receives holes from the substrate; and produces light in response to combining the electrons and the holes.
