摘要
Two-dimensional(2D)cadmium chalcogenides ha ve triggered worldwide interests due to their unique me rits in both structure and physical properties,including thickness-dependent bandgaps,narrow emission line widths high intrinsic absorption coefficient and large absorption cross sections,etc..rendering their great potential for next-generation electronics and optoelectronics devices.In this article,the progress of 2D cadmium chalcogenides in he past few vears is comprehensivelv reviewed.We first discussed several synthetic strategies for various 2D cad mium chalcogenides.Then,their optoelectronic applications in photodetectors,lasers,LEDs,and piezoelectric de-vices are summarized and commented in detail.Finally,a brief conclusion of the article and the future prospects of the 2D cadmium chalcogenides are provided。
