Abstract
The synthesis of silicon nanosheets (SiNSs) without using conventional vacuum processes and vapor deposition is challenging and is anticipated to receive significant attention for a wide range of applications. Thereby, mass production of silicon nanosheets with low cost can be achieved using top-down approach starting from materials including a 2D sheet structure as a fundamental unit. We have recently, developed a soft synthetic method for the preparation of silicon sheets in gram-scale quantities by redox-assisted chemical exfoliation (RACE) of calcium disilicide (CaSi2). In this review, we will present chemical methods for the synthesis and modification of silicon sheets.
