Abstract:

Herein we describe the first synthesis of the layered copper oxide material Sr2Cu03delta carried out under low-pressure and low-temperature conditions. Reaction under these mild conditions was achieved using the pulsed laser ablation and deposition PLD technique,l.2 Structural analyses demonstrate that Sr2CuO3delta prepared by PLD adopts a layered tetragonal structure with a repeat unit consisting of a CuO2 plane and two SrOdelta layers. Investigations of the growth mechanism show that this layered copper oxide phase is a kinetic product in contrast to the thermodynamic one typically produced in solid state reactions. We have exploited this kinetic growth mode to prepare Sr2-xMxCuO3delta solids that have systematic variations in oxygen and cation stoichiometry.
