General description
Dichlorosilane (DCS) is a halogenated silicon based precursor that facilitates the growth of a variety of silane based films such as silicon oxide, silicon nitride, silicon carbide, and epitaxial growth of silica.
Application
DCS is widely used in the synthesis of a variety of silicon-based materials, which find applications in the development of organic electronics based devices, including OFETs, MEMS, NEMS, MOSFETS, and lithium-ion batteries.

The structure and rheological properties of xanthan gum (XG) modified in a cold plasma environment were investigated. XG was functionalized in a capacitively coupled 13.56-MHz radio frequency dichlorosilane (DS)-plasma conditions and, consecutively, in situ aminated by ethylenediamine. The surface structure
