Abstract

A method for producing electrical contacts on organic semiconductors is described. The method, which involves low energy impact and can be carried out under ambient conditions, comprises covering the relevant surface of the semiconductor with a layer of an appropriate solvent such as water; an aluminium leaf having an appropriate thickness and work function containing metal oxide impurities is deposited onto the area treated in this manner. Electrical contacts with elevated conductivity are obtained by evaporating the solvent. One embodiment of the invention describes a family of crystalline semiconductors, preferably based on perylene or α-quaterthiophene, provided with the electrical contacts according to the method described herein and provided with particular structural characteristics.
