Effect of alloying by fluorine on the electrical properties of Bi2Sr2CaCu2O(y) superconductors
Abstract
A series of Bi2Sr2CaCu2O(y)F(x) specimens with varying fluorine contents (x = 0.2, 0.4, 0.6, and 1.0) were synthesized and characterized with respect to their electrical properties. In accordance with X-ray diffraction data, the samples have a nearly single-phase structure with a = 5.4 A and c = 30.6 A. As the fluorine content increases, the type of conductivity changes from metal to semiconductor, which is attributed to a decrease in the concentration of charge carriers (holes) due to alloying.
