Designing indirect–direct bandgap transitions in double perovskites

A general design strategy is presented for tuning the convergence of direct and indirect bandgaps based on chemical adjustment of the s- and p-orbital character of the conduction band minimum. To demonstrate the viability of the design strategy, we successfully synthesized a family of double perovsk...

Description
Summary:A general design strategy is presented for tuning the convergence of direct and indirect bandgaps based on chemical adjustment of the s- and p-orbital character of the conduction band minimum. To demonstrate the viability of the design strategy, we successfully synthesized a family of double perovskites: Cs 2 AgSbCl 6 with an indirect bandgap and Cs 2 AgInCl 6 with a direct bandgap and the solid solutions between the two.
