Figure 4. Weak antilocalization effect in applied magnetic field B||E.
(a) The magnetoconductivity of sample CA1 (hole square) vs magnetic field in B‖E at temperature from 2 K to 100 K along with fitting (red solid curves) to the Equation 3. (b) Temperature dependence of β obtained from Equation 3. For sample CA1, the mean free path 64 nm is larger than the film thickness 50 nm.
