Novel approach to tuning the physical properties of organic-inorganic hybrid semiconductors

We discuss theoretically a novel approach to tailoring the properties of a new family of organic-inorganic hybrid superlattices, using two isostructural materials, $\mathrm{ZnSe}(\mathrm{en}{)}_{0.5}$ and $\mathrm{ZnTe}(\mathrm{en}{)}_{0.5}$, as examples. Replacing Se with Te leads to a number of nontrivial changes: the conduction band parity, singularity type, conductivity in the superlattice direction, and the $p$-type dopability. Experimentally, we report the first unambiguous observation of exciton-polariton emission in a hybrid semiconductor, i.e., $\mathrm{ZnTe}(\mathrm{en}{)}_{0.5}$. The band-edge excitonic transitions in both emission and absorption are explained by the calculated electronic structures.
