Influences of temperature and transport properties on the birefringence of CdGeAs2

We have directly measured the birefringence Δn of CdGeAs2 using polarized light interference spectra obtained in transmittance from 2.4 to 18 μm over a temperature range of 14–450 K. Four different samples, exhibiting a wide range of free carrier concentrations, were studied. It was found that free...
