Wavelength selective charge accumulation in self-organized InAs/GaAs quantum dots
SEMICONDUCTOR SCIENCE AND TECHNOLOGY(2004)
摘要
Wavelength selective charging of a QD sub-ensemble is demonstrated, presenting a basis. of future wavelength dependent parallel. optical memory. High-resolution saturation spectroscopy in, two-colour photocurrent experiments is used to investigate the. binding, energy of the positively charged trion complex as well as the temperature dependence of the coupling to acoustic phonons.
