WebJul 23, 2015 · It was then used to investigate a wide range of vapor deposition conditions spanning high-vacuum physical vapor deposition to low-vacuum gas jet assisted vapor deposition. The average coating thickness was found to increase initially with gas pressure reaching a maximum at a chamber pressure of 8–10 Pa, but the best coating thickness ... WebDec 13, 2024 · Nanocrystalline titanium diboride (TiB2) ceramics films were prepared on a high purity graphite substrate via chemical vapor deposition (CVD). The substrate was synthesized by a gas mixture of TiCl4, BCl3, and H2 under 1000 °C and 10 Pa. Properties and microstructures of TiB2 films were also examined. The as-deposited TiB2 films had …

The nitrogen-doped single-walled carbon nanotubes (N-SWCNTs) are directly deposited on a patterned filter by FCCVD with designable patterns and facilely dry …
WebMar 13, 2014 · The technique may utilize directed vapor deposition (DVD), which is a novel type of electron beam-physical vapor deposition. In DVD, an electron beam is used to form a vapor plume including the coating components, and a stream of gas is used to direct the vapor plume. WebThe vapor deposition method was developed by Choi and Eastman [15] in 2001, and it is one of the most used one-step methods until now. In this method, a fine film of base fluid is generated against the inner surface of a container through centrifugal action by rotating a disk attached to a container.
WebFeb 17, 2024 · Selected area deposition of high purity gold films onto nanoscale 3D architectures is highly desirable as gold is conductive, inert, plasmonically active, and can be functionalized with thiol chemistries, which are useful in many biological applications. Here, we show that high-purity gold coatings can be selectively grown with the Me2Au (acac) … WebElectron-beam physical vapor deposition, or EBPVD, is a form of physical vapor deposition in which a target anode is bombarded with an electron beam given off by a charged tungsten filament under high vacuum. The electron beam causes atoms from the target to transform into the gaseous phase. These atoms then precipitate into solid form, …
