Preparation of La 2− xSr xCuO 4 single-crystalline films by infrared-heated liquid phase epitaxial technique
We have designed a new liquid phase epitaxial (LPE) technique, infrared heated LPE (IR-LPE) technique, using no crucible to avoid a contamination from it. La 2− x Sr x CuO 4 single-crystalline films were grown on the a tetra-axis-orientated bulk single crystals of Zn- or Ni-doped La 2CuO 4 by the IR...
