Offer Description In the context of the global push for sustainable technology, organic electronics stand out as a promising alternative to traditional inorganic electronics, offering advantages such as flexibility, lightweight construction, cost-effectiveness, and energy efficiency. The GRIOT (GReen Insulator for sustainable Organic elecTronics) project is a cutting-edge research initiative aimed at advancing organic transistors (OTFTs) by developing eco-friendly and biosourced components. OTFTs are increasingly recognized for their versatility and low-cost fabrication, making them ideal for applications in flexible displays, sensors, RFID tags, and IoT devices.
This internship offers a unique opportunity to contribute to the forefront of sustainable electronics by focusing on the development of an environmentally friendly insulator, a key component of OTFTs. Your work will help address one of the primary challenges in creating fully green organic transistors—replacing traditional materials with green alternatives while maintaining high performance.
As an intern, you will join an interdisciplinary team combining expertise from the organic electronics group at L2n-URCA and the biomolecules and biomaterials group at FARE-INRAE-URCA. Together, we aim to develop and optimize a green insulator, fabricated from biosourced materials, and implement it within organic transistors. This research represents an important step toward minimizing the environmental impact of electronic devices.
Key Tasks and Responsibilities Fabrication of the green insulator film: You will work on optimizing the deposition parameters for the green insulator material, ensuring that key factors such as surface roughness, film thickness, and homogeneity meet the necessary standards for OTFT gate dielectric performance.
Integration into organic transistors: After successfully fabricating the green insulator, you will integrate it into a complete OTFT device by depositing an organic semiconductor (OSC) layer on top of the insulator and fabricating gold source and drain electrodes using shadow masks.
Device characterization and performance evaluation: You will measure the electrical characteristics (IV measurements) of the fabricated OTFTs to assess the performance of the green insulator within the device. Based on the results, you will identify ways to further optimize both material properties and device fabrication processes.
This hands-on role will give you valuable experience in both material fabrication and electronic device testing, providing a deep understanding of sustainable organic electronics. You will also have the opportunity to work with advanced equipment and gain expertise in thin-film deposition and characterization techniques.
This internship offers the possibility of continuing with a PhD project related to OTFTs, funded by the ANR, making it a perfect stepping stone for students interested in pursuing a research career.
Minimum Requirements:
A degree that qualifies for enrolment in a Master 2 in Research or an equivalent program in physics, materials science, nanoscience, or a closely related field.
A hands-on attitude and enthusiasm for experimental work, particularly in material fabrication and device testing.
Good command of written and spoken English.
