CASES OF RESONANT-TUNNELING IMPORTANT FOR HIGH-T-C CUPRATES

Some basic assumptions made by the present author in his work about c- axis transport in layered cuprates are examined on simple models. Firs t, a one-dimensional model is considered with a localized center sligh tly displaced from the middle df the barrier in order to find out whet her this displacement prevents resonant tunneling. Second, a three-dim ensional model is analyzed with two resonant centers in the median pla ne; the goal is to establish whether tunneling through such centers ca n be coherent. The results provide support for the basic assumptions.
