The magnetoresistance (MR) in post-annealed polycrystalline and epitaxial Bi thin films was discussed. The ring reflection high-energy electron diffraction (RHEED) patterns were shown by the films on Si(100). The results showed an increase in the MR by a factor of 2560 at 5K as compared with 343 for an as-grown epitaxial film was observed due to enhanced carrier mobilities.
