直流電圧を印加したポリイミドフィルム中の可視光照射による空間電荷形成

抄録

The pulsed electro-acoustic (PEA) method has been widely used to observe a space charge distribution in various solid dielectric materials. In this report we applied the method to an investigation of the space charge behavior under a high electric filed with a visible light irradiation. It is well known that a property of the conduction in dielectric materials is affected by the irradiation of light. To observe the effect of the light irradiation on the space charge distribution in polyimide, we measured the time dependent space charge distribution under the irradiation of the visible light using three kind of LED.
