The quantum dot proposed in 1982 has been developed as a basic structure of actually operating nanodevices, such as quantum dot lasers, single electron devices, etc., by semiconductor nanotechnology centering on self-assembled quantum dots.In this comprehensive report, fabrication technologies of the semiconductor nanostructures and optical/electronic properties are discussed, bearing in mind their applicability to deployment of photonic devices.First, after a brief review on the history of semiconductor nanostructures, progress in self-assembled quantum dots is discussed.Then, we discuss various technologies for fabricating the quantum dots and wires in addition to the self-assembled growth technique and optical/electronic properties are discussed.Finally, recent development of quantum dot lasers as well as single photon emitters based on the quantum dots is shown.The quantum dots are promising nanostructures for future photonic and electronic devices.
