Kinetic Study of CVD Reaction by Area-Controlled CVD.

open access: yesJOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 2000
A new method for analyzing the kinetics of CVD reactions is proposed using area-controlled CVD. Catalyst particles were set at the dead end of a narrow straight tube. Water vapor generated at the catalyst from H2 and CO2 was fed into the reaction zone to react with TiCl4, which diffused from the opposite side. Then, TiO2 was formed and deposited on the

Interface‐Driven Control of Vanadium Carbide Micro‐ and Nanocrystal Growth During Chemical Vapor Deposition

open access: yesAdvanced Materials Interfaces, EarlyView.
A wrapped copper–vanadium interface enables reliable chemical vapor deposition growth of vanadium carbide micro‐ and nanocrystals. Adjusting methane supply shifts the process from the formation of many small crystals toward lateral expansion and merging of larger domains, while longer growth increases surface coverage without changing the cubic ...
