Controllable synthesis of non-layered two-dimensional plate-like CuGaSe₂ materials for optoelectronic devices.

ABSTRACT: CuGaSe₂ semiconductor materials, as an important member of the I-III-VI₂ family, have sparked tremendous attention due to their fascinating structure-related properties and promising applications in solar energy storage and conversion. Nevertheless, the controllable preparation of two-dimensional (2D) CuGaSe₂ structures is still a daunting challenge owing to the intrinsic non-layered crystal structure and inaccessible reactivity-matching of multiple reaction precursors, which will seriously impede the much deeper research progress on their properties and applications. Herein, non-layered 2D CuGaSe₂ plates possessing high crystallinity, and uniform size and morphology have been first synthesized by a feasible cation exchange strategy. Because the
