Abstract:

In this thesis, we are focusing on the processing of small molecules organic semiconductors (OSCs) to study the relationship between film morphology, small molecule crystal structure and the electrical performance of the organic devices. Aiming at enhancing the electrical performance and stability of the organic field effect transistors based on p-type OSCs blended with an insulating polymer deposited by solution shearing techniques, namely Bar Assistance Meniscus Shearing (BAMS). In addition, we have also explored the application of the OFETs as X-ray photodetectors for imaging application and, the electrolyte-gated OFETs to study interface events on the gate electrode/electrolyte interface.
