Transparent Si nanosheets with a thickness of 0.37 nm are produced by chemically exfoliating calcium disilicide with propylamine hydrochloride (PA⋅HCl; see picture, Ca white, Si red). The nanosheets have a two‐dimensional silicon backbone and are an order of magnitude thinner than previously reported silicon nanostructures.
