Ab-Initio Study on Adsorption and Diffusion of Au Atoms on Clean Si(001) and H-Si(001) Surface

Key engineering materials (2008)

Wei Wei Ju Tong Wei Li Jing Han You Zheng Xin Tang Xiao Yang Gong

Performing ab-initio total-energy calculations to investigate the adsorption and diffusion processes of the Au atoms with both the clean Si(001)-(1×1) and H-terminated Si(001)-(2×1) surfaces. It was found that, on the clean Si(001)-(1×1) surface, the most stable adsorption sites for Au atoms are middle part of four Si atoms, while on H-terminated Si(001)-(2×1) surface, the most stable sites are the middle part of a Si-Si dimer. The result showed that surface hydrogenation make most stable site transfer and affect the adsorption of Au on Si(001) surface.

Extrinsic Scaling Effects on the Dielectric Response of Grained BaTiO<sub>3</sub> Films

Key engineering materials (2010)

Li Ben Li Li Qiu Su Zhi Qiang Zhen Xin Zhong Li Qing Dong Chen

A set of gradient stresses is used in Landau thermodynamic theory to explain the dielectric diffusion of BaTiO3 films grown on thick copper foils. Every grain in the films is treated as a single domain core that is surrounded by boundaries with low dielectric constant. The dielectric diffusion is mainly induced by the diffusive phase transition caused by the gradient stresses. The low dielectric constant boundaries suppress the peak value of the dielectric constant. The results agree with the experiments.
