On the determination of quantum dot sizes by spectroscopic methods

The dependences of the fundamental transition on the quantum dot size obtained experimentally at various temperatures using different measuring methods are analyzed and compared. A simple analytical relationship for approximation of these dependences is proposed. The possibility to extrapolate the r...
