| Abstract: | Photo-magneto-electrets of kapton-H-polyimide, a
photoconducting material, have been prepared under various magnetic fields.
Formation current, dark depolarization and photo-depolarization current studies
have been reported. Formation current increases and becomes constant after some
time. Saturation current increases with forming magnetic field. The variations
of depolarization current of PMEs of kapton-H-polyimide, show a sharp maximum
and then current decays, becoming constant in about ten min. Total area below
the depolarization current versus time gives an idea about the volume
polarization in the dielectric by simultaneous application of magnetic field
and optical radiation. |
