PIEZO-RESISTIVE CHARACTERISTICS OF SOME ORGANIC SEMICONDUCTING POLYMERS
Abstract
A series of highly conjugated polymers with semi conducting characteristics was examined to determine the piezo-resistive behavior. The resistivities, ranging from 100 to 10 to the 11th power ohm-cm at room temperature and 1840 atmospheres pressure, decreased 100 and, for some polymers, 1000 fold as the pressure was increased to 35,000 atmospheres. Elimination of voids and particle-to-particle contact problems was obtained by the extreme pressures used. A correlation between the extrapolated activation energy for the polyacene quinone radical (PAQR) polymers and the number of fused rings in the aromatic portion of the polymer was obtained. An elemental polymeric semiconductor with high conductivity (i.e. p-type tellurium), was also observed to have a decreasing thermoelectric power with increased pressure and a relatively constant activation energy, both due to the p-type TeO2 impurity.
