Microstructure of strained La2CuO4+delta thin films on varied sub-strates

Jiaqing He, Robert F. Klie, Gennady Logvenov +2

Layered perovskite La2CuO4+delta(LCO) thin films were epitaxially grown on SrTiO3 (STO) and LaSrAlO4 (LSAO) substrates by atomic-layer-by-layer molecular beam epitaxy. The lattice…
