Paper Abstract
A potential materials system that may play a key role in IR spectroscopy applications is PbSe/Pb0.934 Sr0.066Se quantum
well structure. In this work, the characteristic temperature (T0) relationship with laser cavity length was studied for this
material system at three temperature ranges 77<T<150 K, 150<T<300 K, and 77<T<300 K. It was noticed that T0 is
high for short cavity lengths then decreases to an almost constant value after some critical length. The data were best
fitted to a second degree polynomials which can be used to determine these critical values. Also, we analyzed the effects
of quantum efficiency on the characteristic temperature values. Inclusion of theoretical values for the quantum efficiency
due to Auger recombination and leakage current reduces the characteristic temperature T0 in these ranges. It was found
that inclusion of the quantum efficiency decreases the characteristic temperature by 60% for a wide range of cavity
lengths.
