2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/155793We report observations of the Coulomb drag effect between two effectively 2-d insulating a-Si_{1-x}Nb_{x} films. We find that there only exist a limited range of experimental parameters over which we can measure a sizable linear-response transresistivity (ρ_{d}). The temperature dependence of ρ_{d} is consistent with the layers being Efros-Shklovskii Anderson insulators provided that a 3-d density of states and a localization length smaller than that obtained from the DC layer-conductivity are assumed.4 pages, 4 figuresMesoscale and Nanoscale PhysicsDisordered Systems and Neural Networkstext
