My research concentrates on the growth and characterisation of organic thin films with interesting optoelectronic and magnetic properties. The material components are based on polyaromatic molecules such as phthalocyanines, and porphyrins, close analogues to natural products (e.g. chlorophyll). Particular emphasis is placed on developing growth methods to obtain new types of structures and morphologies, and charge-transfer complexes. Applications include organic solar cells, spintronic devices, and biosensors.
