Abstract
The operation of low-background lR extrinsic photoconductor detectors and detector arrays is essentially dependent on the process of spreading time-dependent photocurrent, which is due to low non-steady-state screening of the electric charges in the detectors. The spreading leads to an increase in the photoresponse time, an essential difference between the non-steady-state photocurrents in the circuits of the source contacts injecting free-charge carriers into the detectors and those in the circuits of the contacts that serve as drains for the carriers, and a high non-steady-state cross talk in the detector arrays. The results of the experimental study of all these effects and some others in 36- and 48-element linear arrays (Si:Ga) as well as their theoretical description are presented. The theory developed is in satisfactory agreement with the experimental data. Some consequences of the results obtained, which are important in space-based astronomy applications of such detectors, are discussed.
