Abstract

âº Shape and nitrogen effects are studied for dilute nitride quantum dots using k.p model. âº The s hole state can be lower than the p hole state for ring structure. âº Incorporation of nitrogen can reduce transition energy and increase transition matrix element. âº Volcano shape is preferred due to its greater optical gain properties.
