Figure 3
Temperature dependence of the frequency exponent γ.
Red open squares refer to the strip1; blue full circles refer to the intrinsic GBJ. The value for strip2 is the same as for the GBJ, being the latter the dominant noise source. The horizontal dashed line corresponds to the mean value γ = (1.00 ± 0.01). The solid line is the best fitting curve by using equation (4). The arrows correspond to the temperatures shown in Fig. 2. Note the logarithmic temperature scale.
