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