Abstract:
A method of fabricating a device with spherical quantum dots by a combination of gas condensation and an epitaxial technique, comprising:(a) a quantum dots growth step, in which the quantum dots are grown on a substrate by a gas condensation method; (b) a quantum dots processing step, in which an ultrasonic cleaner is used with an organic solvent to vibrate the substrate on which quantum dots have been grown in step (a), or in which the substrate on which quantum dots have been grown in step (a) is thermally annealed at a high temperature; and (c) an epitaxial layer cover step, in which an epitaxial technique is used for covering the quantum dots which have been processed by step (b) with an epitaxial layer.
