We prepared for Mott–Hubbard-type perovskite La[sub 0.5]Sr[sub 0.5]TiO[sub 3+δ] thin films under an oxygen reduced environment, 5% H[sub 2]/Ar. Control of the partial pressure during deposition could change the conductivity of the films, and induces a metal–insulator transition. In addition, we observed an excellent transparency at visible light with a metallic behavior, where this property could be utilized as a transparent conductor. © 2001 American Institute of Physics.

    Precursor films of 200 nm thickness are deposited on SrTiO[sub 3] single crystals by the coevaporation technique using Y, BaF[sub 2] and Cu. Precursor films including BaF[sub 2] are generally annealed at a low oxygen partial pressure with water vapor. On the contrary, the precursor films in the...

    Stripes of thin gold films are made on an elastomeric substrate with built-in compressive stress to form surface waves. Because these waves can be stretched flat they function as elastic electrical conductors. Surprisingly, we observe electrical continuity not only up to an external strain of...
