Introduction. In 1979, it was proposed [ 1] that a Berezinski–Kosterlitz–Thouless (BKT) phase transition [ 2] in two-dimensional superconducting films could occur, and its possible evidence was linked to the sheet resistance of the films. Later, interest was raised in the possible observation of BKT transition on two-dimensional arrays ...
