| Abstract: | The AC measurement method of zero bias junction impedance(R0) and junction capacitance(Cd) combines with the characteristic of Model 124A Lock-in Amplifier,we produce a novel measurement method of R0 and Cd for photovoltaic HgCdTe infrared detectors.The R0,Cd,? and R0A of the photovoltaic HgCdTe infrared detectors can be measured accurately by the method.The error(<5%) of the measurement is estimated by a normative detectors.Moreover,the method is used to measure the R0 and Cd of other materials photovoltai... |
