Based on experimental results of investigation of type of conductivity of silicon samples doped with sulfur at Т=1250°С, and thereafter with zinc at T=1200°С, the authors put forward the hypothesis about self-assembly of “binary” elementary cells where atoms of elements of group II (Zn) and IV (S) allegedly form ZnS-type compounds in Si. The thermodynamic conditions required for buildup of such elementary cells and assembly of various associations in the basic lattice of silicon including self-assembly of ZnS clusters were theoretically determined and experimentally justified.

Organic functionalization of non-oxidized silicon surfaces, while allowing for robust chemical passivation of the inorganic substrate, is intended and expected to broaden the chemical, physical and electronic properties of the currently most relevant technological material. Numerous protocols are now available for the preparation of Si-C, Si-O and Si-N bound layers. In particular, the covalent attachment of 1-alkenes and 1-alkynes onto hydride-terminated Si(100) and Si(111) has seen a wealth of research activity starting from the pioneering work of Linford and Chidsey (Alkyl monolayers covalently bonded to silicon surfaces, J. Am. Chem. Soc., 1993, 115(26), 12631-12632). This critical review aims to bring …
