  • The selected candidate will work on the different technologicaal blocks including growth of III-nitride heterostructures that is needed for fabricating MicroLEDs

    The mechanical release of III-nitride devices using h-BN is a promising approach for heterogeneous integration. Upscaling this technology for industrial level requires solutions that allow a simple pick-and-place technique of selected devices for integration while preserving device performance. A new technology developed at IRL GT-CNRS satisfies both of these requirements. It is based on a lateral control of the h-BN quality, using patterned sapphire with a SiO2 mask, to achieve localized van der Waals epitaxy of high-quality GaN based device structures. After process fabrication, the devices can be individually picked and placed on a foreign substrate without the need for a dicing step. The goal of this project is to use this technology in order to develop processing that will result in mechanically removable ultra-thin (< 10 micron), 50µm long InGaN LEDs that will be mechanically removed from a substrate and packaged onto a flexible device.
