Abstract
The anisotropy of the photoconduction of polyimide was investigated in relation to the molecular orientation. The photocurrent as well as the molecular chain alignment was found to be anisotropic. A phenomenological model for the photocurrent in different directions of electric field was discussed. The photoconduction phenomena in the in-plane direction and that normal to the film plane were analyzed. The results are used as a foundation for comparing the conduction in the three directions. It was concluded that the anisotropy was caused by the alignment and orientation of the molecular planes as well as the molecular chains.Keywords
