Abstract :
A data-processing approach has been developed to obtain device parameters from resistance-voltage (R-V) characteristics measured on long-wavelength HgCdTe n-on-p photodiodes. A simple carrier density approximation is proposed to take account of carrier degeneracy and conduction band non-parabolicity into its physical model. Some basic parameters of devices can be extracted from measured R-V curves
