Abstract The electronic densities of states of YBa₂Cu₂ScO₇ high T_c materials, including two cases of Sc substituting Cul and Cu2 sites, have been calculated, and the results are compared with that3of YBa₂Cu₃O₇ and Y_0.5Sc_0.5Ba₂Cu₃O₇ systems. Sc-Cu2 replacement will largely influence the electronic structure of Cu-O layers. However, Sc-Cul replacement is more possible.
