Projektbeschreibung
Innovative Technologie für das elektrische Dotieren
Die Halbleiterindustrie greift auf elektrisches Dotieren zurück, um die Ladungsträgerdichte zu beeinflussen. Doch bei vielversprechenden neuen Halbleitermaterialien wie leitenden Polymeren, Fullerenen und Quantenpunkten funktionieren herkömmliche Dotiermethoden nicht. Vor diesem Hintergrund wird das EU-finanzierte Projekt 4D das Anwendungspotenzial einer neu entwickelten Technologie zum bedarfsgerechten Dotieren dieser Materialien untersuchen. Im Rahmen des Projekts werden Demonstratorgeräte entwickelt, um das Potenzial des Verfahrens aufzuzeigen, das geistige Eigentum zu schützen und das Interesse wichtiger Interessengruppen aus der Industrie an dieser Technologie einzuschätzen. Die Technologie wird den Energieverbrauch von Lampen und Displays senken und die Konstruktion hochleistungsfähiger, lösungsverarbeitbarer Solarzellen ermöglichen.
Ziel
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.
