Abstract
The use of an organic material having a conjugated ring system such as 3,4,9,10-perylenetetracarboxylic dianhydride interfaced with a semiconductor material such as silicon yields quite acceptable rectifying properties. These properties are used to test the suitability of the substrate during processing. Additionally, these materials upon irradiation change refractive index, allowing production of optical devices such as gratings. The combination of electrical and optical devices formed using these organic materials also allows relatively simple fabrication of integrated opto-electronic structures.
