Temperature dependence of the resistivity of the sample; the dashed line is the extrapolation of the normal-state resistivity into the low-temperature region. Temperature is marked by an arrow.
Comparison of the experimental curve of versus near (dots) with the fluctuation theories constructed using the parameters indicated in the text: MT contribution (1), AL (3D) contribution (2), LD contribution (3).
Plot of versus (solid curve 1) over the whole temperature interval from to . Curve 2 (dashed) was calculated according to Eq. (6) with the parameters indicated in the text; and bound the interval of exponential dependence of . The inset shows versus (solid curve), the dashed curve being the straight line whose inverse slope determines .
versus calculated according to Eq. (5) for the film (dots) and for the films: F1 (circlets), F4 (squares), and F6 (triangles). The solid curves are a guide to the eye. (see text).
Plot of versus the reduced temperature for the film (dots) and an optimally doped film (sample F1) (circlets). Curves 1–4 show the dependence calculated for different values of the parameter : 10 (1) (the BCS limit); (2); (3); (4) (the BEC limit).
Parameters of the samples.
