Growth evolution of Bi sub(2)Sr sub(2)CaCu sub(2)O sub(8+) sub( delta )thin films deposited by infrared (1064 nm) pulsed laser deposition

Bi sub(2)Sr sub(2)CaCu sub(2)O sub(8+) sub( delta )(Bi-2212) thin films were grown on MgO (1 0 0) using 1064 nm infrared pulsed laser deposition with post heat treatment.

Description
Summary:Bi sub(2)Sr sub(2)CaCu sub(2)O sub(8+) sub( delta )(Bi-2212) thin films were grown on MgO (1 0 0) using 1064 nm infrared pulsed laser deposition with post heat treatment. The material arrives at the substrate surface with characteristic spheroidal morphology. Smooth, homogeneous and highly c-axis oriented films were obtained after heat treatment. Using infrared laser as excitation, the stoichiometry of the target is preserved on the film. However, the films were apparently under-doped.
