Abstract

Single-crystalline Sr1 xLaxCuO2 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 Tonsetc=41.5 K and Tzeroc=39.0 K, which is close to the highest Tonsetc 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 Tc.
