WebJan 27, 2024 · In this paper, the defluorination of SiF4 on Si (1 1 1) surface are studied by adopting density functional theory calculation. SiF4 defluorination on Si (1 1 1) surface will undergo a four-step reaction: (1) SiF4 ↔ SiF3 + F, (2) SiF3 ↔ SiF2 + F, (3) SiF2 ↔ SiF + F, and (4) SiF ↔ Si + F. The results show that SiF3 and F tend to adsorb at the T site, SiF … WebFor a chemical reaction, the equilibrium constant can be defined as the ratio between the amount of reactant and the amount of product which is used to determine chemical behaviour.
