Nanyang Tech University Deploys Aixtron System For LED Research

Apart from being used for gallium nitride research for solid state lighting applications, the CCS will provide a teaching facility for school students in becoming familiar with MOCVD technology.

 

Aixtron SE has announced that Nanyang Technological University (NTU) Singapore, has received its new Close Coupled Showerhead (CCS) system. 

Commissioned by the local Aixtron support team, the CCS 3x2-inch wafer configuration system is being used for research into ultra-high brightness LEDs and related material systems.

Director of Luminous! Centre of Excellence for Semiconductor Lighting and Displays and Singapore NRF Fellow, Nanyang Associate Professor Hilmi Volkan Demir comments, “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 optimisation as well as colour-converting LEDs with high scotopic/photopic ratio."

He continues, “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," concludes Demir.

Demir is a faculty member of the Division of Microelectronics at the School of Electrical & Electronic Engineering and Division of Physics and Applied Physics at School of Physical and Mathematical Sciences. He is a recipient of many prestigious awards including Singapore National Research Foundation (NRF) Fellowship, the European Science Foundation European Young Investigator Award (EURYI), and the Marie Curie Intra-European Fellowship; he completed his PhD at Stanford University, USA.

Luminous! Center of Excellence for Semiconductor Lighting and Displays is focused on various multidisciplinary studies to offer solutions addressing energy efficiency and photometric quality problems in lighting, including the Super-Excitonics Program funded by NRF Competitive Research Program. Luminous! pursues an integrated approach including materials research, device physics, and applications. The MOCVD facility is dedicated to SSL and displays by developing a new class of solid state lighting white LEDs integrated with semiconductor nanophosphors.

*Mesopic vision, the combination of photopic and scotopic vision for low but not completely dark lighting situations, covering light levels with luminances over 0.001 to 3 cd m-2 which includes the majority of night-time outdoor and traffic lighting scenarios.
