International expert meeting IWBNS 2013 discusses technologies and markets for bulk GaN

29.10.2013
The market penetration of bulk GaN crystals is continuing: This is the conclusion of an international expert meeting organized by Fraunhofer IISB.

More than 70 internationally renowned experts met during the 8th International Workshop on Bulk Nitride Semiconductors (IWBNS) from Sept. 30th to Oct. 5th 2013 at Kloster Seeon in order to discuss the current status and future direction of growing bulk nitride crystals. The workshop was organized by Fraunhofer IISB an enjoyed the patronage of the German Association of Crystal Growth DGKK.

Nitride semiconductors are a strong research focus worldwide, since wide band gap semiconductors such as GaN and AlN have turned out to be the best choice for power electronic and optoelectronic devices with enhanced power efficiency or optical performance. GaN LEDs are increasingly dominating global lighting, and electronic GaN devices are expected to achieve a substantial volume in the market soon. However, one of the key requirements for boosting the market share of nitride devices and helping to develop green technologies is the availability of cheap, high quality native substrates, which is expected to have a great impact on the further development of power electronic systems for high power applications and high brightness LEDs and high power laser diodes.

Fraunhofer IISB has more than a decade of experience in the field of bulk nitride semi-conductors and is currently doing research on the HVPE growth of GaN crystals and on the growth of nitrides with the ammonothermal technique. The latter project is in close collaboration with the University of Erlangen - Nuremberg within the “Ammonothermalsynthesis” research group funded by the German Science Foundation DFG. Part of the research of Fraun-hofer IISB additionally focuses on the correlation of the electrical performance of the devices with the quality of the substrates and epitaxial layers. It was therefore a great honor that Dr. Elke Meissner from Fraunhofer IISB was selected by an international steering committee to host the 8th IWBNS workshop.

The IWBNS workshop is the only expert meeting in the world that is specially dedicated to the science and technology of the crystal growth of bulk nitrides. About the number of participants, the eighth IWBNS workshop was the largest one ever held. More than seventy renowned international experts from ten nations in Asia, the United States, South America and Eu-rope gathered for the first time in Germany at the beautiful, scenic location of Kloster Seeon in southern Bavaria.

It was an amazing meeting with an extremely high scientific level due to the outstanding contributions of the participants. The workshop covered the crystal growth and technology of GaN, AlN, InN and other binary nitrides. “The quality of the papers was the highest of the five of these meetings I have attended,” said James Edgar from Kansas State University. Jan Weyher from the Polish Academy of Science commented, “It was a very stimulating workshop, perfectly organized.”

The IWBNS has classic individual scientific spirit, intensity and character. It is designed to implement and increase an intense exchange of information that is as open as possible as well as deep scientific discussion and collaboration among academic, industrial, and government scientists regarding the challenges of growing high quality group III nitride crystals with a low concentration of structural defects and a controlled conductivity type. The very dense program of the 8th IWBNS clearly demonstrated the great necessity for further intensive exchange among experts in this field in order to further promote the penetration of the wide band gap materials into the market for energy efficient LEDs and power devices.

The organizers of the 8th IWBNS workshop gratefully acknowledge the support of several organizations that helped to make the meeting successful and the generous support for the participation of young scientists by the German Association of Crystal Growth DGKK and the International Union of Crystallography IUCR.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
