Calcium Di-silicide: A potential precursor for chemical synthesis of functionalized Bi-dimensional silicon materials

Nanostructured silicon materials having nanometers thicknesses and lateral dimensions ranging from the submicrometer to the micrometer scale, communally called silicon nanosheets (SiNSs), are predicted to have higher physical proprieties than bulk silicon materials. Thus, the design of two-dimension...

Description
Summary:Nanostructured silicon materials having nanometers thicknesses and lateral dimensions ranging from the submicrometer to the micrometer scale, communally called silicon nanosheets (SiNSs), are predicted to have higher physical proprieties than bulk silicon materials. Thus, the design of two-dimensional (2D) silicon nanomaterials has attracted a great attention, but their functionalization with organic compounds remains a huge challenge. Calcium disilicide (CaSi2) is by far the source material used for the synthesis of SiNSs via topchemical deintercalation of silicide. In this review, we describe the recent advances of surface modifications of SiNSs with various organic substrates by a top-down strategy.
