Abstract:Global energy minimum structures and optoelectronic properties are presented for isolated CdxSey+ clusters with x + y ≤ 26. The compositional‐ and size‐dependent variation of optical, electronic and geometric properties is systematically studied within the framework of ground state and time‐dependent density functional theory. The applied methods are justified by benchmarks with experimental data. It is shown that the optical gap can be tuned by more than 2 eV by only changing the composition for a fixed numbe… Show more
