Metal-like state in undoped polymer films: techniques of inducing and properties

Summary form only given. An abnormally high sensitivity of the conductivity of thin polymer films to some external influences, such as uniaxial pressure, electric field, temperature, electron beam has been discovered. A common feature for all these phenomena is that they are shaped as the dielectric-metal phase transition which are initiated by external influences of the abnormally low values. The latter include uniaxial pressure, electric field, electron beam and temperature. The present paper discusses experimental results obtained during the investigations of the phenomena.
