摘 要:The atomic and electronic structures of amorphous CuxZr100-x(x=36,46,50,56,64) alloys were simulated using first-principle calculations within a 400-atom *** pair correlation function,coordination numbers,local cluster structures and electronic density of states were *** agreements between the theory and the experiments were *** amorphous alloys exhibit different local cluster structures and can all be explained with cluster formulas [cluster](glue)1,3,where the clusters are derived from known Cu-Zr *** is always a pseudogap in the density of state at the Fermi level.
