  • We investigated the crystal structure and electronic properties of Bismuth tungstate Bi2WO6 by first-principles calculation based on the Density Functional Theory. The calculated electronic density of states confirmed that Bi2WO6 possess the semiconducting properties with the band gap of 2.198 eV. The contribution of each atomic orbital to electronic densities of states was evaluated from the partial densities of states.

  • Various mesoscopic systems have their own unique characteristics, some of which are of importance due to bridging function over classical and quantum mechanics. It is quite natural that human beings living in macroscopic world could hardly grasp the phenomena occurring in the microscopic world in an intuitive manner. This situation offers a vital sense in the "observation" problem necessarily accompanied with the classical means. The fundamental core of the argument between Einstein-Podolsky-Rosen and Bohr starting in 1935 actually lies in this point.
