Product of mobility and lifetime of charge carriers in CdTe determined from low-frequency current fluctuations
Original language description
The model, which clarifies the low-frequency fluctuations of the current flowing in CdTe sample, makes it possible to determine the product of the mobility and lifetime of the charges in mentioned semiconductor. This model, with general validity for semiconductors, is based on the interaction of shallow traps with the valence or conduction band. As a result of the action of these centers, current fluctuations appear, the mean amplitude of which increases linearly with the inverse value of the frequency. It was found that the slope of this dependence is proportional to the product of mobility mu and a constant which is common to all shallow traps and which is denoted by the symbol a. The lifetime of charges located on shallow traps varies according to the relationship tau = a/f and for fmin it acquires a maximum value of tau max, which agrees with the stationary lifetime. For the p-CdTe crystalline semiconductor the mobility-lifetime product mu p tau p = (6.6 +/- 0.3) x 10-7 cm2V-1was obtained. Similar study of n-type CdTe showed mu n tau n = (7.5 +/- 0.3) x 10-8 cm2V-1.
