摘要：

In this paper we report resistivity measurements as a function of temperature for Cu/Ti superlattices of periods of 20, 50, 100, 200, and 400. We find that the in-plane resistivity is inversely proportional to the layer period; in the sample with the smallest period, there is a sharp drop to a negative value of the temperature coefficient of resistivity, which is positive and roughly constant for the other layer periods. This agrees with results for the Cu/Nb superlattice and indicates weak localization in the 20- sample. © 1990 The American Physical Society.
