Abstract

The characteristic temperature calculations and dependency on cavity length was analyzed for Pb_0.934Sr_0.066 Se multiple Quantum well Structure at three temperature ranges 77<T<150 K, 150<T<300 K, and 77<T<300 K. In this work, we show the behavior of the characteristic temperature as a function of cavity length and were able to best fit the data to a second degree polynomial. Inclusion of theoretical values for the quantum efficiency due to Auger recombination reduces the characteristic temperature T₀in these ranges. It was found that inclusion of the quantum efficiency decreases the characteristic temperature by a factor of 0.6 for a wide range of cavity lengths. When results were compared to experimental data, it was concluded that there is a leakage current above the barrier due to thermionic emission. The leakage current density was estimated to be around 5423 A/cm² at room temperature. With this high value more work is needed to understand the thermionic emission process to improve on the performance of this material system and similar ones.
