The structure and growth mechanism of a Bi cuprate formed by low-temperature MBE are discussed. Examination of the X-ray diffraction of the ultrathin films revealed that the lattice constants of an ultrathin film of Bi 2201 are affected by the lattice constants of the substrate. The key process of the low-temperature epitaxial growth realized by the usage of NO2 is also discussed in correlation with the oxidation mechanism of deposited metals with NO2 examined by X-ray photoelectron spectroscopy.
