Physics of organic-organic interfaces

This thesis focused on the experimental study of a variety of organic-organic heterojunctions that have applications in organic devices. Organic-organic interfaces are inhered for plastic electronics, which is promising alternatives to epitaxially grown, inorganic electronics. However, before organic-based electronics become widespread in daily live much effort is required. Not all organic semiconductors-based devices perform sufficiently to be of commercial interest. Thus, the understanding and the control of the processes determining the properties of organic semiconductors is crucial to the further development of organic electronics. In this work, by combining spectroscopy and microscopy techniques, the nature of the interactions between the materials and the influence on the final properties of the hetrojunction was investigated.
