N. Hatta et al., Two-to-three dimensional transition by magnetic field on weak localizationphenomena for tilted magneto-conductance in In2O3-x films, PHYSICA B, 298(1-4), 2001, pp. 482-485
To study the two-to-three dimensional transition on the weak localization p
henomena in thin metallic In-2 O3-x films, we have carried out the magneto-
conductance measurements for those films with various thickness up to the m
agnetic field of 9 T. We have measured the magneto-conductance as functions
of the film thickness and the angle between the directions of the electric
current and the magnetic held. From the magnitude correlation between the
film thickness and the cyclotron diameter, we found that the anisotropic be
havior of the magneto-conductance observed in the low magnetic held has bee
n disappeared as the magnetic held increases. As a result we have clearly o
bserved the two-to-three dimensional transition of the electronic system an
d the crossover effect on the positive magneto-conductance in the weak loca
lization regime. (C) 2001 Published by Elsevier Science B.V.
