SiO 2 thin films were deposited with atomic layer control using self-limiting surface reactions. The SiO 2 growth was achieved by separating the binary reaction SiCl 4+ 2H 2 O → SiO 2+ 4HCl into two half-reactions. Successive application of the hal

The adsorption and desorption kinetics of H2O were studied on a well-defined, fully hydroxylated SiO2 surface. The measurements were performed on a planar, thin SiO2 film grown on Si(100) using chemical vapor deposition techniques. The experiments we

The atomic layer control of SiO2 growth can be accomplished using binary reaction sequence chemistry. To achieve this atomic layer growth, the binary reaction SiCl4 + 2H2O → SiO2 + 4 HCl can be divided into separate half-reactions: (A) SiOH ∗
