Dmitry Porotnikov, Mikhail Zamkov
Abstract
Two-dimensional (2D) semiconductor nanocrystals processed from solution have become an attractive material platform for the development of optoelectronic devices. The synergy of the 2D charge carrier confinement and soft fabrication methods has enabled new paradigms in solid-state lighting, biosensing, and energy harvesting. In this Perspective, we will summarize recent research trends in the synthesis and applications of 2D semiconductor materials, focusing on three morphological classes: metal chalcogenides, halide perovskites, and transition metal dichalcogenides. Our aim is to describe the role that 2D geometry plays in the optical and electronic properties of these semiconductor nanostructures and to discuss emerging opportunities in their synthesis and applications.
