Energetic barrier reduction at the carbyne film interface

An abnormal injection current density through SiO2 has been observed recently for both signs of charge carriers in experiments with an oriented carbyne film grown on a SiO2 layer. The absence of a surface leakage current and the insulating property of SiO2 were experimentally proved. The temperature dependence of the current through SiO2 showed low activation energy and confirmed the model of thermally activated injection. A strong influence of the electric field applied transverse to the carbon chains on the current through SiO2 was observed. A model of energetic barrier reduction at the carbyne interface based on the hypothesis of transverse inter-chain hopping in the electric field was proposed. It was shown that a transverse electric field can be induced in a carbyne film as in one-dimensional media. The first organic light emitting device with a carbyne-based effective injector was fabricated.
