| Application: | Tris(dimethylamino)silane can be used: • As a silicon source for deposition of aluminum silicate on TiO2 anodes for dye-sensitized solar cells vis atomic layer deposition method. • As a precursor to fabricate functionalized Si reinforced separators for Li-ion batteries. |
| General description: | Tris(dimethylamino)silane is an organosilicon compound with high volatility and thermal stability, widely used as a vapor deposition precursor to fabricate silicon-containing thin films for various applications, including solar cells, fuel cell catalysts, and semiconductors. The depositions can be carried out at low substrate temperatures (<150). The melting point and vapor pressure of TDMAS is in a suitable working range, thus making it a very good vapor deposition precursor. |
