Presentation Title
Temperature Dependent Charge Transport Characteristics of Ferroelectric Organic Field Effect Transistors
Abstract
This presentation will outline my recent research in ferroelectric organic field-effect transistor (Fe-OFET) fabrication. This research took a top-gate bottom-contact OFET design I had previously used and adapted it to suit Fe-OFETs through the introduction of a P(VDF-TrFE) dielectric layer. I will present my experimental methodology that led to the successful fabrication of Fe-OFETs. This will be followed by the results I found in the characterization of these transistors. These results include measurements taken at room temperature as well as temperature dependent measurements, where one of my samples was cooled and heated under high vacuum. Together, these results provide insight into the temperature dependence of the charge transport mechanisms present in the transistors I fabricated.
