Zeeman Effect of Bound Excitons in II-IV-V2Chalcopyrite Semiconductors

We present an analysis of the Zeeman effect of bound excitons in II-IV-${\mathrm{V}}_2$ chalcopyrite semiconductors and compare our results with those in wurtzite semiconductors like CdS. We also present experimental data on Zeeman studies of sharp luminescence lines in ZnSi${\mathrm{P}}_2$ and identify the most prominent emission line in the spectrum as due to an exciton bound to an ionized or isoelectronic impurity.
