【 摘 要 】

The theoretical approach proposed recently to describe the redistribution of electronic charge in multilayered selectively doped systems is modified for a system with a finite number of layers. Special attention is payed to the case of a finite heterostructure made of copper-oxide layers which are all nonsuperconducting (including nonconducting) because the doping levels in them are beyond the characteristic interval for superconductivity. Specific finite structures and doping configurations are proposed to obtain atomically thin superconducting heterojunctions of different compositions.
