Chemical vapor deposition - Wikipedia

Chemical vapor deposition (CVD) is a vacuum deposition method used to produce high quality, high-performance, solid materials. The process is often used in the semiconductor industry to produce thin films.. In typical CVD, the wafer (substrate) is exposed to one or more volatile precursors, which react and/or decompose on the substrate surface to produce the desired deposit.

Ultralow-temperature photochemical synthesis of atomically .

In this article, we largely decreased the reaction temperature for ultraviolet (UV) photochemical reduction of H 2 PtCl 6 solution to −60 °C and demonstrated such a method as a fast and convenient process for the synthesis of atomically dispersed Pt. We showed that the ultralow-temperature reaction efficiently inhibited the nucleation .

Photochemical Activity of Black Phosphorus for Near .

The photochemical activity of black phosphorus (BP) in near‐infrared (NIR) light controlled in situ biomineralization is investigated. Owing to the excellent NIR absorption, irradiation with NIR light not only promotes degradation of BP into PO 4 3−, but also enhances the chemical activity to accelerate the reaction between PO 4 3− and Ca 2+ and promote in situ biomineralization.
