Optical probing of charge traps in organic field-effect transistors

Objective

Organic electronics offers huge potential for fabrication of large-area, low-cost, and efficient devices. Solution processing and availability of a vast library of organic semiconductors enables to exquisitely tailor properties to each application, while minimising waste of materials and maintaining low temperatures during processing thus reducing energy use. Although organic electronic devices have reached the market in large and flexible displays, their real potential in biomedical applications, sensing, and sustainable electronics remains unrealised. Crucial fundamental building blocks, such as organic field-effect transistors, are still hindered by limited charge mobility and unpredictable outcomes with new material recipes. Organic semiconductor performance is significantly reduced by formation of charge traps, which are local defects in the material or interfaces that remove charge carriers from the device conduction channels and obstruct transport. Accurate control of charge traps is critical to boost device performance, but they are notoriously difficult to identify, characterise and rationally engineer. OPTOCHARGE adopts a novel approach to optically stimulate traps with high spatial, temporal, and energy resolution, and reveal the key parameters for charge trap optimisation. The project systematically explores crystallinity, morphology, material blends, dopants and electrolyte gating to dissect the origin of traps and offer effective strategies to boost device performance. The proposal leverages unique interdisciplinary synergies between applicant and host, and provides an outstanding research setting to fulfil the full potential of the applicant and launch his academic career.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
