N2 - We investigate the crossover from the ballistic, through the diffusive, into the localized transport regime by calculating the conductance and conductance fluctuations in different microstructures. The crossover is induced in two ways; by increasing the disorder strength while keeping the constriction length fixed, and by increasing the constriction length while keeping the disorder strength fixed. We show that the two methods result in qualitatively the same behavior. Two types of microstructures are studied; a smooth bottleneck constriction and a rectangular strip. We also illustrate how the filtering effect of the bottleneck constriction changes during the crossover between different transport regimes.
