Superconductivity is one of the most amazing phenomena in condensed matter physics. Initially, superconductivity was limited to low temperatures, but research has since developed to find High Temperature Superconductors (HTSC). Among these, cuprates have had a remarkable impact. These cuprates were first identified as semiconductor materials and later found to exhibit superconducting properties. In this …
