Low-temperature liquid-phase epitaxy of YBa sub(2) Cu sub(3) O sub(y) films by the molten KOH method

We fabricated high-performance YBa sub(2) Cu sub(3) O sub(y)(Y123) films by the liquid-phase epitaxy method using molten KOH flux at low temperatures. The Y123 films fabricated in N sub(2) atmosphere showed biaxial orientation above 500 [degrees]C; moreover, the surface morphology of the Y123 films...

Zusammenfassung:We fabricated high-performance YBa sub(2) Cu sub(3) O sub(y)(Y123) films by the liquid-phase epitaxy method using molten KOH flux at low temperatures. The Y123 films fabricated in N sub(2) atmosphere showed biaxial orientation above 500 [degrees]C; moreover, the surface morphology of the Y123 films fabricated above 650 [degrees]C suggested spiral growth. The Y123 films fabricated above 650 [degrees]C showed a sharp transition with a (ProQuest: Formulae and/or non-USASCII text omitted) of 90 K.
