Application of a distinctly bent, trinuclear, end-to-end azide bridged, mixed valence cobalt(III/II/III) complex in the fabrication of photosensitive Schottky barrier diodes

A trinuclear cobalt(III)-cobalt(II)-cobalt(III) complex has been synthesized and used to fabricate a Schottky barrier diode. The conductivity of the synthesized complex-based device improves considerably in illumination conditions from the non-illuminated conditions.
