Abstract

The photogeneration of electrons and holes in thin polycrystalline iodoform films has been investigated as a function of the electric field. Equal values of the primary rates of production of electrons and holes support the idea of an intrinsic photogeneration mechanism. The experimental results are fitted by the Onsager model. The fraction of absorbed photons that produce thermalized electron-hole pairs is found to be close to unity, with an initial pair separation of ca. 3 nm.
