The conducting polymer/polymer interface

Abstract

It is well-known that interfaces between various substances are widely used in modern electronics. Recently it has been found out that the interfaces of two dielectrics can possess unusual electronic properties. This work shows that high-conductivity interface can be obtained not only on the boundary of two crystals but also on the interface of amorphous insulator polymers with the carrier mobility extremely high for organic materials (0.4 cm2/Vs). Conductivity of the structure exceeds the bulk conductivity of the materials used by more than five orders of magnitude. Moreover, the polymer/polymer interface has a metallic conductivity.

Smart Polymers as Basic for Bio-, Chemical and Physical Sensors

“…These phenomena were explained in the framework of the hypothesis that a two-dimensional electron gas is formed in the extra layer between two insulators. At the same time anomalously high conductivity at the interface between two identical polymer layers of poly(diphenylenephthalide) has been demonstrated [22].…”

New Organic Polymers for Solar Cells

“…Otherwise, charge carrier transport across the interface will be limited by the barrier. The tunneling model of Fowler-Nordheim (FN) and Richardson-Schottky's (RSch) thermionic emission model are usually used to study injection in polymers in a rather strong electric field [29][30][31].…”

Фотопроводимость Вдоль Границы Раздела Полимер/Полимер

“…В отличие от неорганических структур проводимость и подвижность носителей заряда в случае полимерной границы ниже. Тем не менее, они превышают объемные параметры по проводимости на 8 порядков, а по подвижности на 5−6 порядков [8]. Возможно более низкие значения этих показателей были обусловлены высоким уровнем дефектности границ раздела полимер/полимер, обуслов-ленным технологией получения этих границ (центрифугирование растворов и термический отжиг).…”
