   Abstract:
   Time-resolved mid-infrared-pump, optical-probe differential transmission spectroscopy on n-doped quantum dots directly reveals electron dynamics relevant to unipolar devices. Capture times into excited and ground states are found to be 7.1 and 116 ps. © 2005 Optical Society of America.
