Design and evaluation of high-k dielectric materials for low-power 'green' OFET-based sensors

Abstract

This thesis aims to design and focus on the exploration of OFET-based sensors using solution-processed polymeric dielectrics and organic semiconductors. It also investigates the potential of synthetic and natural polymeric dielectrics blended with nanoparticles on capacitors. The thesis is organised into five chapters: The first twochapters consist of the published review articles on OFET and OPT devices. They provide a comprehensive background on these devices, supported by examples from literature, along with explanations of the mechanisms of the devices. The third and fourth chapters present the experimental research findings related to capacitors and OFET devices, offering new insights and data. The last chapter summarises the results, evaluates the research, discusses the challenges encountered, and concludes the thesis with planned recommendations for future work
