Aixtron CRIUS MOCVD system ordered for University of Duisburg-Essen’s NaSoL nitride nanowires project

In Q4/2009, deposition equipment maker Aixtron AG of Aachen-Herzogenrath, Germany received an order for a CRIUS MOCVD deposition system from the University of Duisburg-Essen’s Semiconductor & Optoelectronics Center. The 3x2-inch configured system, equipped with an ARGUS multichannel pyrometer, will be delivered in Q2/2010and used for the university’s nitride nanowire NaSoL Project.

NaSoL (“Halbleiter-Nanodrähte für Solarzellen und Leuchtdioden”, which translates as “Semiconductor nanowires for solar cells and LEDs”) aims to create a new generation of semiconductor nanowires for solar cells and LEDs, and replace traditional semiconductor fabrication techniques with MOCVD. Nanowire-based materials are said to be more efficient in absorbing and emitting light, and also promise very low losses in energy transport. The nanoscale coaxial core-shell heterostructure of these devices has a larger surface area, so it absorbs more light and delivers better efficiency, it is claimed.

“We selected the Aixtron CCS system as part of the university’s initiative to acquire a nitride material system for the nitride nanowire NaSoL Project. Our experience with Aixtron equipment goes back a long way - we were one of their very first customers. The reactor’s combination of features including the minor/low rotational velocity is also very impressive. Overall, we have always been very satisfied with the quality of Aixtron engineering, processes and service. Of course, we also took into consideration our project partnership. The NaSoL Project aims to achieve production of GaN- and (Al,Ga,In)N-based semiconductor nanowires for improved efficiency solar cells and LEDs,” said Prof. Dr. rer. nat. Franz-Josef Tegude, chair of Semiconductor Technology.

Partners in NaSoL are Aixtron AG, the University of Duisburg-Essen’s Center for Semiconductor and Optoelectronics (ZHO) and the Department of Electronics Materials and Nanostructures. The research project was formally approved and started during Q3/2009.
