摘要: Exploration of the Stranski-Krastanow growth strained semiconductor hetero structures marked major breakthrough for easy fabrication defect-free quantum dots (QDs). For first time, single QDs are facilitating development electrically operated emitters polarized or entangled photons on demand: an essential component communication systems. inserted in wells, stacked planes upon each other, have led to lasers that can operate at wavelengths were previously impossible, least difficult reach, a given family. These show excellent temperature stability, large radiation resistance, and temporal spatial stability. In this review we discuss recent progress field dot devices.
