A pseudopotential energy band calculation is carried out for a hypothetical crystal which corresponds to Cd 3 P 2 and Zn 3 P 2 . From these results, the conduction band effective masses as well as the interband transition assignments associated with the optical reflectivity peaks are deduced. The temperature dependence of the energy gap for these materials is estimated and d E g /d T is shown to be negative.
