Abstract

We have demonstrated simultaneous anion and cation exchange processes to grow novel optoelectronic structures that are unlikely to be grown directly. While separate anion or cation exchange process has been demonstrated before, this is the systematic demonstration of simultaneous exchanges of both anions and cations. In this study, we particularly focus on ZnCdSSe quaternary alloys and CdSe-rich alloys provided an appropriate starting material for morphology transfer through simultaneous dual-ion exchange processes to obtain ZnS/Se-rich ZnCdSSe nanosheet structures. This mechanism is very promising to grow a variety of structures not possible to be grown directly with desired morphology and composition combinations.
