Temperature dependence of photoluminescence characteristics of excitons in stacked quantum dots and quantum dot chains

Osamu Kojima, Hiroaki Nakatani, Takashi Kita, Osamu Wada, and Kouichi Akahane We have investigated the effects of temperature on the photoluminescence (PL) characteristics of excitons in ordinary stacked quantum dots (QDs) and QD chains in which QDs are interconnected along the growth direction. While the temperature dependence of the PL intensity of both samples is similar, ... [J. Appl. Phys. 107, 073506 (2010)] published Wed Apr 7, 2010.
