description: Understanding and controlling the flow of charge carriers lies at the heart of today's society as it is the basis for the successful operation of electronic devices. Here, the charge transport properties of organic semiconductor thin films will be investigated. The first part of this work focusses on the fundamentals of charge transport in such films starting with investigations into metal-insulator semiconductor capacitors. A robust and widely applicable approach to measure the charge carrier mobility in semiconductors will be presented next, enabling a novel way to measure this important transport parameter with minimal influence of the commonly occurring injection barriers. Further investigations into the local electrical properties of a transistor under operation condition are carried out. The second part of this thesis is focused on detailed studies into two material classes bearing potential applications in the field of organic electronics. It is shown that the prototypical organic semiconductor Poly(para-phenylene) indeed possesses semiconducting properties in its unsubstituted form. The materials crystallinity was further improved through careful precursor design. Cinnamic acid derivatives are further shown to cross-link under electron radiation. This finding is applied in a semiconducting polymer which preserves its semiconducting properties even after electron beam patterning.
