Ultralow Resistivity in Langmuir-Blodgett Heterofilms of Much Less than the Metal Resistivity and Ultrahigh Current Density

Abstract

Ultralow resistivity in Langmuir-Blodgett (LB) heterofilms of much less than the metal resistivity was briefly reported in the previous paper, and such remarkable characteristics seem to be due to the two-dimensional potential well with electron gas generated in the LB heterofilms. In the present paper, detailed data of the ultralow resistivity are described with data related to temperature (room temperature ∼75°C) and ambient air pressure. The minimum resistivity of 4.0×10^-12Ω·cm was measured; furthermore, an ultrahigh current density of 2.0×10⁶ A/cm² was observed.
