Abstract
The influence of the growth temperature T-s on the structure, optical absorption, and electrical conductivity of BiSrCaCuO films has been st udied. It was observed that nonmonotonic changes in the parameters of the films with T-s are caused by (111)double right arrow(001) phase tr ansitions at T(s)approximate to 550 degrees C for the 2212 phase and T (s)approximate to 600 degrees C for the 2223 phase. These phase transi tions stimulate the formation of metallic conductivity and are caused by a change in the system of preferential ordering planes of the atoms .
