Phonon localization in ultrathin layered structures
An efficient way for minimizing phonon thermal conductivity in solids is to nanostructure them by means of reduced phonon mean free path, phonon scattering and phonon reflection at interfaces. A sophisticated...

Experimental Study of Texture and Self-Polarization of Sol-Gel Derived PZT Thin Films
Pb(Zr,Ti)O3 (PZT) thin films have been reported to show a significant polarization after deposition without any previous poling treatment which is referred to as self-polarization. This effect has also been found...

Ba2Cu3O5+δ as an intermediate phase during the synthesis of YBa2Cu4O8
We propose a reaction model for the synthesis of YBa2Cu4O8 under normal pressure conditions, which contains 4 partial reaction steps. In a first step bariumnitrate and copperoxide react to Ba2Cu3O5+δ. This substa...
