The role of various CuO single crystal surfaces in the superconductivity of the CuO-Cu interface

The analysis of superconducting states in the interface CuO-Cu depending on the spraying of Cu atoms on the xz, yz, xy faces of monocrystal CuO is done in the Shubin-Vonsovskiy approximation. It is shown that the highest value of critical temperature $T_c \sim$ 300 K can be obtained using the spraying of atoms on the yz face. The spraying of Cu atoms on the other faces leads to the superconducting states with the small values of $T_c \sim$ 10 K.
