Abstract
Methods and systems are provided for a photoconductive thin film of a plurality of Lead Selenide (PbSe) nanostructures arranged on quartz substrates. The photoconductive thin film is synthesized, for example, using a chemical bath deposition, and can include a tunable iodine doping process to select the size and/or shape of the nanostructures. An oxygenation sensitization process at a sufficiently high temperature can increase carrier mobility of the thin film.
Claims13
A photoconductive thin film, comprising:
- a substrate;
- and
- a plurality of polycrystalline lead selenide (PbSe) nanoparticles arranged on the substrate, the nanoparticles containing a threshold amount of iodine dopant,
- wherein a carrier mobility of the thin film is approximately 80 cm2 V−1 s−1.
