The phase transition from an orthorhombic phase (space group Pnma ) to a rhombohedral phase (space group R 3 m ) of the CdHfO 3 hafnate is investigated using methods of structural analysis. It is shown that crystal lattices of both phases contain polar structural units (octahedra, cubooctahedra)....
Ba 0.85 Sr 0.15 TiO 3 ferroelectric films on single-crystal silicon wafers were grown and studied. X-ray diffraction and electron microscopy studies showed that the films are characterized by a limited texture with a perovskite structure. It was shown that the grown films can be used as recording...
The electrical and luminescence properties of a poly(amidoamine) (PAMAM) dendrimer containing naphthalimide are investigated. The influence of adsorbed oxygen on the electrical conductivity of thermally evaporated organic films is analyzed using cyclic thermal desorption. The results obtained are...
The freezing and melting phase transitions for gallium embedded into a porous glass with a pore size of about 8 nm were studied using acoustic, NMR, and x-ray techniques. It was shown that the broadened solidification and melting transitions upon deep cooling up to complete freezing at 165 K were...
