Abstract

Epitaxial Fe-Te-Se thin films were deposited by pulsed laser deposition at 250-600 °C on SrTiO₃ (100, STO), MgO (100), LaAlO₃ (100, LAO) and CaF₂ (100) single crystal substrates. Best superconducting film was grown on CaF₂: T_c^onset = 20.0 K and T_c⁰ = 16.18 K with T_dep = 300 °C, 45000 pulses, 3 Hz. The critical current density J_c at 4.2 K was 0.41 × 10⁶A/cm² at 0 T and 0.23×10⁶ A/cm² at 9 T. Angular dependence of J_c showed broad c-axis correlated peak when B ≥ 3 T.
