Tuning the optical properties of dilute nitride site controlled quantum dots

Research output: Chapter in Book/Report/Conference proceedingsChapterpeer-review

Abstract

We show that deterministic control of the properties of pyramidal site-controlled quantum dots (QD) could be achieved by exposing the QD layer to nitrogen precursor unsymmetrical dimethylhydrazine (UDMHy). The properties that could be tuned include an expected emission reduction in dilute nitride materials, excitonic pattern (biexciton binding energy) and improved carrier confinement potential symmetry (reduced fine-structure splitting).
