Adsorption of a metalloid, boron (B) on W(100) was investigated using low energy electron diffraction (LEED), X-ray photoelectron spectroscopy (XPS) and scanning tunneling microscopy (STM) in ultra-high vacuum (UHV) condition. W(100)-c(2 × 2)-B superstructure formed by annealing at high temperature (1200 K). The best fit structure obtained from LEED analysis STM observation manifested that B at...

A convergence structure generalizing the order convergence structure on the set of Hausdorff continuous interval functions is defined on the set of minimal usco maps. The properties of the obtained convergence space are investigated and essential links with the pointwise convergence and the order convergence are revealed. The convergence structure can be extended to a uniform convergence struct...

Using transmission electron microscopy, a new nano-phase structure of Zn0.75Ox induced by Zn-vacancy has been discovered to grow on wurtzite ZnO nanobelts. The superstructure grows epitaxial from the f0 110g surface of the wurtzite ZnO nanobelts and can be fitted as an orthorhombic structure, with lattice parameters a 0Z2a, b0z ffiffiffi 3 p a and c 0Zc, where a and c are the lattice parameters...
