A research group led by Professor Hiroshi Amano and Associate Professor Atsushi Tanaka (specially appointed) of the Institute of Materials and Systems for Sustainability developed a lossless short-time laser slicing technique for GaN1)<\/span><\/sup><\/strong> substrates in cooperation with Hamamatsu Photonics K.K.<\/span><\/p>\r\n Monocrystal GaN substrates are indispensable for high-performance devices using GaN substrates. However, the high price of GaN substrates prohibits their widespread use. The achievement of this study will lead to a significant reduction in the fabrication cost of devices using GaN substrates and their increased use in society.<\/span><\/p>\r\n Part of this research was conducted under contract of R&D for the expansion of radio wave resources (JPJ000254) and strategic information and communications R&D promotion programme (JP215006003), organized by the Ministry of Internal Affairs and Communications, Japan.<\/span> [Points]<\/span><\/strong><\/p>\r\n <\/p>\r\n 1)<\/sup><\/span><\/strong>Gallium nitride (GaN): GaN has high-performance characteristics as a power semiconductor and is commonly used as a light emitter in LEDs and other devices.<\/span><\/p>\r\n Related published journal papers<\/span><\/strong><\/p>\r\n \"Smart-cut-like laser slicing of GaN substrate using its own nitrogen\"<\/span> Scientific Reports, May 31, 2022<\/span><\/p>\r\n DOI: 10.1038\/s41598-021-97159-w<\/span> Scientific Reports, May 31, 2022<\/span><\/p>\r\n DOI: 10.1038\/s41598-022-10610-4<\/span> Designated Associate Professor Atsushi Tanaka,
