摘要：

A Kronig Penney periodic pair potential model is proposed for YBa2Cu3O7 with the pair potential only depending on the coordinate parallel to the c-axis. Numerical results for the 3-D density of states are compare with existing tunneling data. As a main result, oscillations in the high energy tunneling characteristics can be attributed to energy bands resulting from the periodic potential. © 1990, Elsevier Science Publishers B.V.
