A cluster model study of the electron-phonon interaction magnesium diborate

Research output: Contribution to journalArticle

Abstract

A cluster model of the electron-phonon interaction in magnesium diborate was studied. Magnesium diborate is a new superconductor with temperature constant at 39k. Boron formed stacks of honeycomb layers with magnesium as a space filler as in graphite intercalation compounds. Scanning tunneling and high resolution photoemission spectroscopy measurements showed the temperature dependence of the superconducting gap. Electron-phonon coupling suggested high transition temperature that came from the significant coupling caused by the presence of holes in the top of the band. The orbital-vibronic coupling to understand the frontier orbitals couple with the molecular vibrations was also studied.
