CHARACTERIZATION AND ELECTRICAL PROPERTY OF MOLTEN-GROWN CUTCNQ FILM MATERIAL

Metallic copper foil directly reacted with molten TCNQ (7,7,8,8-tetrac yano-p-quinodimethane) under nitrogen atmosphere resulted in a CuTCNQ semiconducting film with electrical switching and memory properties. T he material was characterised by Raman and UV-Vis spectral analyses as well as current-voltage characteristic measurement. The degree of cha rge transfer from copper to TCNQ and the electrical memory switching p roperty are discussed. The spectral analyses, degree of charge transfe r and electrical property are compared with those of both metathetical ly synthesised pure CuTCNQ powder and a solution-grown film material.
