Material transfer dynamics of infrared 1064 nm Nd: YAG pulsed laser deposition
Abstract
Bi2Sr2CaCu2O8+δ (Bi-2212) films were prepared by infrared 1064 nm Nd: YAG pulsed laser deposition. The material arrives at the substrate surface as molten stoichiometric blocks of Bi-2212 and form clusters of immobile spheroids. Crystal facets of Bi-2212 were exposed with heat treatment, this further proofs the material is stoichiometric when they arrive on the substrate that reconfigure and eventually re-orient on the substrate axis upon heat treatment. Flat, smooth and homogeneous films of Bi-2212 that reproduce the chemical structure and composition of the starting material were deposited by this method.
