Abstract
The method for measuring the anisotropy of photocurrent along three orthogonal directions in polymer films was proposed. Oriented poly(ethylene 2,6-naphthalate) films were employed as samples, photocurrent along the fiber axis increased with drawing, whereas that along the direction normal to film planes decreased. The anisotropy of electronic conduction resulted from the orientation of crystallites was measured, for the first time, in an insulating polymer film which has no π-conjugated system of electrons in molecular chains.
