Abstract
We have prepared Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}} (Bi-2212) thin films by a pulse laser deposition (PLD) method followed by post-annealing. The thin films were grown on MgO substrates at 400-630 deg. C and 100 mTorr oxygen. They were about 200 nm thick. The crystalline structure of thin films deposited at lower temperature ({approx}470 deg. C) was amorphous. The films deposited at higher temperature ({approx}550 deg. C) began to crystallize (c-axis oriented) but it turned out that Bi decreased with an increase temperature. After deposition, post-annealing were performed at 860-880 deg. C in a tubular furnace with mixed gas (Ar:O{sub 2} = 93:7, 1 atm, 0.2 l/min flow) for 3 h. Bi did not decrease with the increase of post-annealing temperature up to 870 deg. C. The critical temperature of film was 78 K, and the root-mean-square (RMS) roughness in 10 {mu}m square was less than 10 nm.
