Abstract

A series of Alx-(Alq3)1-x granular films is prepared on Si wafer with native oxide layer using co-evaporation technique. Large lateral photovoltaic effect (LPE) is observed, with an optimal LPV sensitivity of 75 mV/mm in x = 0.35 sample. The dependence of LPE on temperature and Al composition is investigated, and the possible mechanism is discussed.
