Optical anisotropy in the Pb2Sr2(Y, Ca)Cu3O8+δ superconductor

Cellular automata model for persistent photoconductivity in YBCO

“…Next we turn our attention to the increase in average chain length, l. We would like to directly correlate this with an increase in mobility. We think that such an association is reasonable because optical measurements on crystals show that increasing the chain length (oxygen content) results in a lower scattering rate, and hence mean free time [19,20]. Extrapolating the infrared conductivity measurements of [20] to near DC frequencies shows that the carrier effective mass is not dramatically different for fully oxygenated YBCO as it is for oxygen deficient material.…”

“…5,6 Oxygen ordering in the Cu-O chain plane can be observed by studying the change in the 4-eV transition. 12,13 As a result, the amplitude of the imaginary part of the dielectric function at the CP scales with the actual oxygen content in the compound. The dimensionality of the CP, characterized by the ͑temperature-dependent͒ line shape of the CP, has been subject of two studies.…”
