摘要: | The superconducting transition temperatures T-C of face-centered cubic Al1-x-Li-x alloys (x = 0-0.10) exhibit a minimum near x = 0.03 (3 at.% Li). The McMillan strong-coupling T, equation yields a similar trend of the electron-phonon coupling constant.. Meanwhile, the density of states at the Fermi level N(0) decreases monotonically with increasing x. It appears that T-C drops initially due to a reduced N(0), which is then overtaken by alloying-enhanced factors of phonon or electron-phonon interaction. (c) 2007 Elsevier Ltd. All rights reserved. |
