Scanning electron microscope investigations of highly conducting organic composites

Scanning electron microscope (SEM) investigation of the highly conducting organic composites of general formulae (BEDT-TTF) ₓ /(AuI) and (BEDT-TTF) ₓ /(AuI₃), where BEDT-TTF is bis(ethylenedithio)tetrathiafulvalene, obtained by direct charge-transfer (CT) reaction in the solid state is performed.

Beschreibung
Zusammenfassung:Scanning electron microscope (SEM) investigation of the highly conducting organic composites of general formulae (BEDT-TTF) ₓ /(AuI) and (BEDT-TTF) ₓ /(AuI₃), where BEDT-TTF is bis(ethylenedithio)tetrathiafulvalene, obtained by direct charge-transfer (CT) reaction in the solid state is performed. The granular structure of the composites with domination of three types of the grains: (BEDT-TTF)₂I₃, (BEDT-TTF)₂AuI₂ and Au, is suggested. The changes in the composite structure caused by their composition and/or thermal treatment are connected with the d.c. electrical conductivity of the samples.
