Abstract
In the past 25 years, quantum dots (QDs) have emerged to power a variety of novel optoelectronic and nanotechnology devices and products. Looking to the future, semiconductor quantum dots have been suggested by theoretical works to be candidates for realization of next-generation lasers, photodetectors, and other light- and information-processing devices. Control of the size and position of QDs incorporated into semiconductor devices, or a so-called site-controlled quantum dot (SCQD) technology [1], is a necessary precursor for advanced QD-based devices. A plausible method to create SCQDs, which is widely considered feasible for mass-production, has not to date emerged. This is perhaps the major stumbling block forestalling widespread introduction of next-generation QD-based optoelectronics. © 2010 IEEE.
