Charge Transfer at Metal Oxide/Organic Interfaces
… charge transfer between metal oxides and organic semiconductors has been found to limit the efficiency of organic optoelectronic devices. Although a number of investigations of inorganic/organic systems exist, very few generally applicable rules for oxide/organic interfaces have been …

Electronic properties of metal-organic and organic-organic interfaces studied by photoemission and photoabsorption spectroscopy
In this work systematic studies of the organic semiconductor CuPc have been presented. In general the investigation can be devided in three parts. In the first one we have studied the electronic structure of clean CuPc thin film. The next two parts are devoted to organic-organic and metal–organic …

Investigating Complex Organic Species on Mineral Surfaces
… is presented, with the aim to understand mineral-organic interfaces. It is demonstrated that despite silicate rock being dominated by silicates, the exposed surfaces of the rock is not reflected in the bulk composition. This leads to a range of mineral surfaces and functional groups at the surface …
