Structural Dimensionality Control of Organic-Inorganic Metal Halide Hybrids
Abstract
The proposed research aims to develop and study novel organic-inorganic metal halide hybrids with controlled compositions, structures, and dimensionalities. Its main thrust involves identification and understanding of phenomena and mechanisms associated with synthesis and processing of hybrid materials containing various metal halides as the building blocks with three- (3D), two- (2D), one- (1D), and zero-dimensional (0D) structures, which can display unique optical/electronic properties with applications in optoelectronic devices. Organic-inorganic metal halide hybrids are an emerging class of crystalline materials with exceptional structural and functional tunabilities for optoelectronic properties. To advance the frontier from the well-known 3D and 2D perovskites to new crystal structures with potentially novel properties, the proposed research will develop synthesis and processing approaches to assemble organic metal halide hybrids with different dimensionalities that exhibit unique properties. A variety of characterization techniques will be utilized to gain insights of the nucleation mechanisms and growth kinetics to understand how the organic cations, inorganic anions, and synthetic conditions affect the crystal formation and structure. A comprehensive understanding of the structure-property relationships is a major goal, and applications of these new materials in optoelectronic devices will be explored. The success of this project will provide fundamental understanding of the physical/chemical phenomena that underpin structure formation and crystallization mechanisms of single crystalline organic-inorganic metal halide hybrids, which will guide the development of next generation low cost high performance hybrid materials with unique and exceptional optical/electronic properties for a variety of applications.
