摘要：

Transport properties of SrCuO2 thin films with and without the artificial modulated structures formed by periodical incorporation of extra Sr layers as (SrCuO2)10Sr by MBE are presented. The resistivity of the film is found to decrease by one order of magnitude when they are post-oxidized in situ. For the films with an extra Sr layer (double Sr-layer formation) for every ten units of SrCuO2 cells, an anomaly in resistivity is observed around 100 K which coincides with the reported T(c) of the high-T(c) superconductor of infinite layers.
