dc.description.abstract | We report the effect of oxidation on PbS quantum dot (QD) photodetectors using rapid thermal annealing (RTA) and furnace annealing in air at different durations and temperatures. Air-annealed QD films using RTA had an improved specific detectivity of up to 1.51 X 10(12) Jones with a responsivity of up to 1.895 X 10(3) A/W at 1 kHz. We used transient photocurrent decay measurements, X-ray photoelectron spectroscopy, and frequency response measurements to investigate the origin of this effect. We found that short-term annealing with RTA in air increases the product of carrier mobility and carrier lifetime (mu tau) of the QD photoconductors, which leads to high photoconductive gain and bandwidth. | - |
