Optimizing Performance of Far-Infrared Photoconductors: New Approach for Interpretation and Calibration of Transient Response

The goals of the proposed work were to determine if final steady state current values for Ge:Ga photoconductors could be predicted from the initial fast component of the transient response and to develop algorithms to operationalize this approach. This required transient measurements as a function of photon background and signal sizes, for both single shot and modulated signals. In addition, we proposed to address the nature of the hook response and the effects of non-equilibrium background fluctuations
