Theoretical Study of Electron-Phonon Interaction in ZrB2 and TaB2 | | Prabhakar P. Singh

7 Feb 2003 | | Journal: | Phys. Rev. B 69, 094519 (2004) | | Subject: | Superconductivity; Materials Science | cond-mat.supr-con cond-mat.mtrl-sci | | Abstract: | Using full-potential, density-functional-based methods we have studied electron-phonon interaction in ZrB2 and TaB2 in P6/mmm crystal structure. Our results for phonon density of states and Eliashberg function show that the electron-phonon coupling in ZrB2 is much weaker than in TaB2. In particular, we find that the average electron-phonon coupling constant lambda is equal to 0.14 for ZrB2 and 0.72 for TaB2. The solutions of the isotropic Eliashberg gap equation indicate no superconductivity for ZrB2 but a superconducting transition temperature Tc of around 12 K for TaB2 with mu* ~0.16. | | Source: | arXiv, cond-mat/0302134 | | Services: | Forum | Review | PDF | Favorites | |
