Epitaxial growth of Bi 2 Se 3 thin films is of great current interest due to the advantages in spintronics and thermoelectrical applications. In this paper, Bi 2 Se 3 thin films on Si (111) substrate have been prepared via magnetron sputtering deposition with post-annealing treatment and their microstructures and electrical transport properties were studied. Good quality with highly c-axis oriented films could be obtained after post-annealing treatment. The annealing temperature (T a ) obviously affected the phase structures and electrical properties. The crystallinity and the lattice parameters c of the Bi 2 Se 3 thin-films increased with increasing T a . The relative atomic ratio of Se / Bi decreased with increasing T a and large number of Se vacancies was discovered in films with T a = 350° C . The resistivity of films decreased monotonously and showed weakly metallic resistivity with the increase of T a . Non-saturated high-field linear magnetoresistance and weak antilocalization were found in films with higher T a .

ABSTRACTAntidot arrays were formed in thin films of bismuth by the e-beam evaporation of the metal on the porous surface of porous anodic alumina templates. The magnetoresistance of the antidot array films was measured and compared to that of films deposited on glass slides. A significant difference in magnetoresistance behavior was observed, and this difference was attributed to the enhancement of the two dimensional weak antilocalization effect in the antidot arrays. Scattering rates were obtained by fitting the experimental results to the theoretical expression. The results indicate that the antidot morphology enhances the elastic scattering rate over the inelastic scattering rate.
