Nanyang Technological University to Utilize Aixtron System for Solid State Lighting Research

LIGHTimes News Staff

November 3, 2011…Aixtron SE announced that Nanyang Technological University (NTU) Singapore, has received its new Close Coupled Showerhead® (CCS) system. The CCS system in the 3×2-inch wafer configuration was commissioned by the local Aixtron support team. Aixtron reports that it is being used for research into ultra-high brightness LEDs and related material systems.

“We have established a solid-state lighting (SSL) lab to develop cost-saving, green solutions to generate and harvest light. Already we have fabricated and tested nanostructured white LEDs of nanocrystal quantum dot emitters for high quality mesopic* SSL. Areas where the CCS system will be absolutely vital include III-N epitaxy, doping engineering and epitaxial growth optimization as well as color-converting LEDs with high scotopic/photopic ratio," stated Director of Luminous! Center of Excellence for Semiconductor Lighting and Displays and Singapore NRF Fellow and Nanyang Associate Professor Hilmi Volkan Demir (NTU School of Electrical & Electronic Engineering and School of Physical and Mathematical Sciences). Demir added, "So we are looking to apply our new Aixtron system to some fairly challenging but highly promising areas of lighting development. My team is already familiar with the high technical standard of this equipment and has great trust in the excellent Aixtron local support, so I think we can be sure all our enquiries will be dealt with efficiently. Moreover, as well as being dedicated to GaN LED research, the CCS will provide a much needed teaching facility for our school students getting familiar with MOCVD technology. So, in more than one way the CCS is already proving its usefulness and will continue to do so for many years to come.”

Luminous! Center of Excellence for Semiconductor Lighting and Displays is focused on offering solutions addressing energy efficiency and photometric quality problems in lighting, including the Super-Excitonics Program funded by NRF Competitive Research Program.
