WebOct 1, 2010 · The probability of tunneling at the Fermi energy through a junction between two conductors is proportional to exp (− T1 / T0 ). Despite the high values of T0 and T1, the T1 / T0 ratios for our samples were almost identical to those reported for the single-walled carbon nanotube (SWCNT) networks. WebJun 26, 2024 · In this case, an insulating behavior at low temperatures is observed, which can be well explained by employing the fluctuation-induced tunneling (FIT) model. At medium iodine doping concentrations, both metallic and insulating behaviors can be observed at different temperatures, implying that both FIT and metallic mechanisms take … WebJul 29, 2015 · In addition, fluctuations in the free-electron density on either side of the junction give rise to large voltage fluctuations that modulate the effective tunneling barrier.
