Detection of the biochemical species in the environmental pollution, industrial emission monitoring, medical diagnosis, public security, agriculture and a variety of industries has resulted in the emerging need for a generation of high density nanostructured sensor arrays. The fundamental two terminal and three terminal device components because of their potential for specificity eventually have to be integrated into miniaturized and portable nanoarray sensors. One of the key components in these nanosensors is the development of building functional building blocks that improve device performance capabilities. This research is focused on methodology for developing fundamental, functional, multiscale architecture model system for generating high density nanoscale two terminal structures for future integrated circuits for sensor applications. The key idea is to design and characterize a nanomaterial junction array that can demonstrate diode like electrical behavior. A hybrid methodology for fabricating this basic nanoelectronic building block, its performance capabilities and its limitations is presented. A soft lithography and standard photolithography techniques are integrated in assembling nanomaterial composites of p- and n- type material to form a junction, which are characterized by using standard electrical characterization methods.
