Abstract
Crystalline Bi1.8Pb0.2Sr2Ca2Cu3O10+x films deposited at substrate temp eratures t(s) from 400 to 700 degrees C were characterized by x-ray di ffraction, optical absorption, and resistivity measurements. The effec t of t(s) on film structure and the role of different atomic arrangeme nts in metallic conduction are examined. The nonmonotonic dependence o f the physical properties of the films on substrate temperature is att ributed to a second-order phase transition at t(s) similar or equal to 600 degrees C associated with structural ordering.
