Designing Devices by Doping on Demand

Project description

Innovative technology for electronic doping

The semiconductor industry relies on electronic doping to control charge carrier density. However, promising new semiconductor materials like conductive polymers, fullerenes, and quantum dots cannot be doped by traditional methods. In this context, the EU-funded 4D project will investigate the application potential of a newly developed technology for doping these materials on demand. The project will include the development of demonstrator devices to exhibit the technique’s potential, protect the intellectual property and analyse the interest of key industry stakeholders in this technology. The technology will reduce the energy consumption of lamps and displays and allow the creation of highly efficient solution-processable solar cells.

Objective

Electronic doping, the control over the charge carrier density, is at the heart of the success of the semiconductor industry. Promising new semiconductor materials like conductive polymers, fullerenes and quantum dots cannot be doped by traditional doping methods. The applicant and his group have developed a general method to dope these materials on demand with an electrochemical method, combined with photopolymerization of the solvents and electrolyte ions. This methods allows to precisely control the charge density in these new semiconductor materials and also allows patterning of the doping density via methods akin to photolithography used in the semiconductor industry. This enable the design of new device geometries, such as lateral pn junctions that could allow easy on chip integration of e.g. solution processable LEDs. The goal of this proof-of-concept application is to investigate the application potential of this newly developed technology. In particular it involves the development of demonstrator devices to showcase the technique’s potential, to investigate and protect the intellectual property and to analyze the interest from key industrial stakeholders in this technology. When successful, this technology has the potential to revolutionize the semiconductor industry. It could be of great economic potential and in addition may contribute to achieving sustainability goals by reducing energy consumption of lamps and displays and by offering new and improved means to harvest solar via highly efficient solution processable solar cells.
