The performance of organic semiconductor thin films in electronic devices is related to their crystal structure and morphology, with charge transport mobility dependent on the degree of crystallinity and on the crystallographic orientation. Here organic molecular beam deposition of vanadyl phthalocyanine is studied on graphene and it is shown that...

Using conductive atomic force microscopy, we introduce a method to simultaneously acquire electrical space charge limited current measurements and material properties such as Young's modulus and surface adhesion, with nanoscale resolution. We demonstrate the utility of this method using thin films of the prototypical, semiconducting polymer poly-3-...

Recent requirements for low cost energy solutions have led to increased research in the area of organic photovoltaics (OPVs), on account of their potential flexibility, low cost and large scale manufacture. The success of these devices, however, has been hampered by low carrier mobilities, resulting in poorly performing devices. Whilst bulk propert...
