Organic molecule modified silicon surface

Although a number of alternatives to silicon-based materials have been proposed, silicon remains the basic material of electronic industry. Recently the research of silicon surface modified by organic molecules has become the highlight in surface chemistry. Organic monolayers covalently attached on silicon surface present stable, reproducible and well-controlled solid surfaces and possess many advantages compared with other surfaces, which will contribute more functions to Si-based materials and microelectronics. In this paper, the recent progress is presented on the methods, characterizations and applications of silicon surface modified by monolayers of organic molecules. Furthermore, the paper brings forward perspectives toward in-depth investigation of organic molecules grafted silicon surface.
