Regarding superconductivity in apical F-type pulsed laser deposition (PLD) thin films, we focused on the deposition process that realizes the bonding and composition, assuming that the BaO₂ and Ca₂Cu₃O_y(O,F)₂ layers serve as the carrier reserve layer (CRL) and superconducting layer (SCL), respectively. Bonding was controlled primarily by deposition temperature (T_CRL, T_SCL), while composition was controlled by deposition time (t_CRL, t_SCL). As a result, a superconducting transition with Tco = 95.2 K and Tce = 45.2 K was achieved at an applied external magnetic field B_app = 0 T.
