摘要：

Extremely flat surfaces of high-T(c) superconductors (HTSCs) are needed for physical measurements and for tunnel device applications because of the very short coherence lengths of HTSCs. Unprecedented materials problems have so far prevented such flat layers from being obtained. The present work describes partially established prerequisites of liquid phase epitaxy (LPE) of HTSCs, so that layer-by-layer growth and thus single-crystalline epitaxial layers of NdBCO could be achieved for the first time. Surface flatness is proven by differential interference contrast microscopy and Talystep measurements.
