Popis: Conducting polymer hybrid systems such as PPy(Li + DBS -) exhibit novel time- and potential-dependent conductivities that can be used to create dynamic memory. The bulk-dominated electronic behavior of conducting polymer hybrids is expected to have superior scaling properties to interface-dominated devices such as CMOS transistors or storage capacitors. In this letter, the scaling properties of the potential-dependent current transients in electrochemically deposited PPy(Li + DBS -) coplanar junctions are examined from 5 to 45 μm. Static and dynamic electronic device behavior leads to the conclusion that carrier conduction in these systems is highly anisotropic with ratios in the range of 50150:1. © 2011 IEEE.
