The preparation and characterization of crystals of the superconducting polymer, (SN)_x

Abstract

A technique is described for growing (SN)x crystals which have superior electrical properties to those reported previously. The room temperature electrical conductivity has increased, so has the ratio of the room temperature and 4°K resistivities. There is no conductivity maximum in the region 20-30°K and the superconducting transition temperature is higher. © 1975.
