Abstract
The main laws of electron transport in layers of lead sulfide (PbS) nanoparticles deposited from aqueous ethanol suspensions were determined by analysis of their current–voltage characteristics. Optical spectra measured at wavelengths in the region of 3500 nm showed that these layers contain almost no any organic components. The photocurrent in deposited PbS nanopowders exhibits variation under the exposure to broadband radiation corresponding to “transparency window” of the atmosphere (8000–14 000 nm), in which the absorption on free charge carriers can take place.
