Keywords: Bi-2212 thin films, pulsed laser deposition

The surface morphology, microstructure and transport properties of the thin films are clearly a function of deposition temperature and post-annealing conditions.It is seen from our experimental data that post- annealing is required to obtain a single phase and to form a smooth surface. Also, the critical temperature is increased due to post annealing.The recrystallized films showed a leaf -like grain morphology and a significant improve ment of Tc, strongly suggesting that the process of amorphization by thermal annealing maybe an effective way to obtain a c-axis oriented Bi-2212 films with improved superconducting properties.
