摘要：

Perfect unit cell-by-unit cell growth of RBa2Cu3O7-delta (R; rare-earth metals) was first demonstrated by means of X-ray diffraction. The superlattice of [(YBa2Cu3O7-delta)1/(PrBa2Cu3O7-delta)1]10 was grown by means of reactive evaporation (RE) with reflection high-energy electron diffraction (RHEED) intensity oscillations. No aperiodicity and no intermixing of YBa2Cu3O7-delta and PrBa2Cu3O7-delta due to the interfacial roughness were found, indicating that the RE-growth monitored in situ by RHEED oscillations makes the exact unit cell growth possible following the two-dimensional growth manner.
