Gusev O. K., Svistun A. I., Shadurskaya L. I., Yarjembitskaya N. V. Design and control of metrological characteristics of photoelectric semiconductor converters with the multiple-charge impurities

 

Initial data for the design of metrological characteristics of photoelectric semiconductor converters with the deep multiple-charge impurities are obtained. Ranges of energy response conformity with linear law are investigated. It was found that photoelectric semiconductor converters with prefixed bandpass, improved signal-to-noise ratio and higher operation temperature can be designed by selection of deep multiple-charge impurity type. It was shown that the technique of photoelectric semiconductor converters spectral response control can be realized by combination control and measurement optical channels in a single photodetector.

Keywords: photoelectric transducer, multiple charged impurity, metrological performance.
