Kyma Collaboration with RPI in GaN LED Technology Featured in Semiconductor Today

Kyma Technologies, Inc., a leading supplier of ultra-high purity crystalline gallium nitride (GaN) and aluminum nitride (AlN) materials and related products and services, has been collaborating for the past few years with the research group of Dr. Christian Wetzel, the Wellfleet Career Development Constellation Professor, Future Chips, and associate professor of physics at Rensselaer Polytechnic Institute (RPI) on advanced GaN light emitting diode (LED) technology.  Kyma announced today the latest results of this highly productive collaboration.

In a newly published Applied Physics Letters paper entitled “Wavelength-stable cyan and green light emitting diodes on nonpolar m-plane GaN bulk substrates,” led by RPI Professor Dr. Theeradetch Detchprohm, a leading scientist in Wetzel’s group, the RPI team demonstrates improved GaN LEDs properties they fabricated on Kyma’s m-plane GaN substrates.  The article can be accessed at http://link.aip.org/link/?APPLAB/96/051101/1.

These new findings by the RPI – Kyma team were also featured yesterday (February 9th) in an article by Dr. Mike Cooke in the industry – leading digital magazine Semiconductor Today.  That article can be found online at http://www.semiconductor-today.com/news_items/2010/FEB/KYMA_090210.htm.

Kyma’s Chief Scientist Dr. Tanya Paskova, who is a co-author on the paper, commented: “This very nice work by our RPI colleagues confirms again the close connection between the properties of the substrate and the device that is fabricated thereupon.  The importance of low defect density nonpolar GaN with zero stacking faults is increasingly clear.  The RPI team is a leader in the GaN LED research community and they are great collaboration partners.  We look forward to many new results yet to come.”
