Disorder and plasmonic effects in the two-dimensional model for high-critical-temperature superconductors.

Type of article: Article

Summary

The effect of disorder on the phononic-plasmonic microscopic model for high-critical temperature superconductors has been studied. The dynamic screening of the Coulomb interaction due to the disorder results in a decrease in critical temperature. For a two-dimensional electronic system the plasmon modes are strongly affected by disorder. Taking this effect into consideration, the authors show that critical temperature can decrease but there is also an additional effect to the phonon-plasmon attractive contribution.
