Quantum dots have attracted considerable interest for their atomic-like properties in recent years.The quantum dots grown by epitaxial self-assembly via Stranski-Krastanow growth mode have many favorable properties for infrared application,such as higher operational temperature,increased signal-to-noise ratio,reduced dark current,wider spectral range and sensitivity to normal incident ra- diation.They are potential candidates for developing a new class of infrared detectors.Some of the latest published developments in the fabrication techniques of quantum dots abroad are summarized and reviewed in this paper.
