Abstract

Charge generation, injection and recombination in quantum dot-sensitized ZnO nanowires was probed using time resolved terahertz spectroscopy. The mobility spectrum at different representative pump-probe delays showed similar behavior during the injection time indicating free charges on the nanowire structures.
