PRE2023-Operando and In-situ Multimode Characterization of Organic Semiconductors (PID2022-136802NB-I00)

Organic semiconductors (OSCs) have emerged as a breath-taking prospect, promising a new era of electronic devices with unparalleled versatility and eco-friendliness. Their applications span a wide spectrum, encompassing organic light-emitting diodes (OLEDs) that bring life to vivid displays, organic photovoltaics that harness the sun’s energy, and organic field-effect transistors that drive the future of flexible electronics. Yet, to truly unleash their full potential across these diverse fields, there are still key challenges that requires fundamental research to advance our understanding on their physical properties at different length scales, which are ultimately related with the control over the structural order and morphology. Sitting at the intersection of physics and chemistry, the study of organic semiconductor films provide an avenue for investigating captivating physico-chemical properties. In this PhD project, we aim at pushing the boundaries of knowledge by operando and in-situ characterization of organic semiconductors thin films to achieve a microscopic understanding of dynamic processes occurring during growth or thermal annealing in correlation with their electrical properties. This research work combines advanced characterization methodologies techniques, including x-ray diffraction, Scanning Probe Force Microscopy, and electrical measurements.
