Single-crystalline Sr₁ _xLa_xCuO₂ thin films of electron-doped infinite-layer compounds were grown by molecular-beam epitaxy. Crucial to our success was the use of KTaO₃ substrates. The best film showed T^onset_c=41.5 K and T^zero_c=39.0 K, which is close to the highest T^onset_c of 43 K for the bulk value. The resistivity of the optimum-doped film exhibited metallic temperature dependence with a low resistivity of 320 μΩ cm at room temperature and 120 μΩ just above T_c.
