Abstract
Using pulsed laser deposition ultra-thin DyBa2Cu3O7-x films were deposited on a single terminated (0 0 1) SrTiOr(3) substrate. The initial growth was studied by high-resolution electron microscopy. Two different types of inte rface arrangements occur and were determined as: bulk-SrO-TiO2-BaO-CuO-BaO- CuO2-Dy-CuO2-BaO bulk and bulk-SrO-TiO2-BaO-CuO2-Dy-CuO2-BaO-CuO-BaO-bulk T his variable growth sequence causes structural shifts, resulting in antipha se boundaries with displacement vector R = [0 0 1/3]. as well as local chem ical variations.
