Dielectric constant in terms of force
WebThe dielectric constant of a substance is the ratio of the permittivity of the substance to the permittivity of the free space. It shows the extent to which a material can hold electric flux … WebRecently, the projected phononic force-constant tensors and atomic Hirshfeld surfaces are also suggested to be useful descriptors for screening of MVB solids. In parallel, a hypervalent bonding mechanism is proposed instead to explain the novel phenomena in PCMs, which advocates an electron-rich scheme (3 center – 4 electron).
