摘要：

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 T-c(onset)=41.5 K and T-c(zero)=39.0 K, which is close to the highest T-c(onset) of 43 K for the bulk value. The resistivity of the optimum-doped film exhibited metallic temperature dependence with a low resistivity of 320 mu Omega cm at room temperature and 120 mu Omega cm just above T-c.
