Multilayer mirrored sapphire substrates for more efficient blue-white LEDs (2020)

Project number: KC-PI-2020/44

Duration of the first phase: 01.04.2020. – 30.09.2020.

Project scientific leader: Dr. Phys. Juris Purans

On May 25, 2017, an agreement No. KC-L-2017/17 was signed between the Latvian Investment and Development Agency and the Institute of Solid State Physics, University of Latvia on receiving support Cabinet Regulation No. 692 of 25 October 2016 “Operational Program“ Growth and Employment ”1.2.1. Specific support objective “Increase private sector investment in R&D” Regulations for the Implementation of the Measure “Support for the Improvement of the Technology Transfer System” within the framework of the Fund for Commercialization and Patenting of Research Results of Public Research Organizations.

On March 31, 2020, within the third project selection round, the Latvian Investment and Development Agency approved the project application “Multilayer mirrored sapphire substrates for more efficient blue-white LEDs” of the Institute of Solid State Physics of the University of Latvia, identification number KC-PI-2020/44.

Project aim: To develop and commercialize novel Ga2O3-based multilayer sapphire substrates, which can be used for LED structure overgrowth in mass production to fabricate more efficient blue-white HB-LEDs. Our mirrored sapphire substrates are designed to show significantly higher light extraction efficiency and increased light emission performance compared to conventional HB-LEDs. LEDs are widely used in street, industrial and household lighting, therefore, a few percent increase in their efficiency would convert to enormous energy savings over longer periods of time.

During the 1st phase, a feasibility study and a commercialization strategy of the technology transfer project are to be developed.

The maximum support funding for the technical and economic feasibility study of the project and the development of the commercialization strategy is up to 25,000.00 euros, including the European Regional Development Fund funding of 25,000.00 EUR.
