A previously unknown mode of conduction is identified in insulating polymers at moderate fields (40-50 MV/m). This takes the form of coherent charged pulses with a mobility (∼10 -10 m 2V -1s -1) several orders of magnitude larger than that traditionally associated with independent charge carriers (∼10 -14 m 2V -1s -1). It is shown that this phenomenon is consistent with a mechanism in which a charged compression boundary is formed electro-mechanically during injection and thereafter travels as a coherent solitary wave (soliton) through the polymer.

Abstract
A previously unknown mode of conduction is identified in insulating polymers at moderate fields (40-50 MV/m). This takes the form of coherent charged pulses with a mobility (∼10 -10 m 2V -1s -1) several orders of magnitude larger than that traditionally associated with independent charge carriers (∼10 -14 m 2V -1s -1). It is shown that this phenomenon is consistent with a mechanism in which a charged compression boundary is formed electro-mechanically during injection and thereafter travels as a coherent solitary wave (soliton) through the polymer.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
