Growth of Nd1.85Ce0.15CuO4+δ thin films by laser ablation
Abstract
We report the sucessful preparation of Nd1.85Ce0.15CuO4+δ thin films grown by laser ablation. By carefully controlling the oxygen content of the film through high temperature vacuum anneals it is possible to obtain a superconductor with a transition temperature which has an onset at 21 K. The high temperature annealing can result in a copper deficient surface. Through the use of energy dispersive X-ray analysis we have adjusted the growth …
