Dependence of photoconduction noise on temperature: A check of barrier‐type theory of photoconductivity in CdS based devices

A theory of current noise in photoconducting devices developed in a previous paper has been checked against measurements of photoconductance noise in a CdS based device as a function of temperature. It is shown that the theory reproduces the experimental results without the introduction of free parameters in the low frequency range where the photo‐induced component dominates the whole power spectrum.
