Industrialization of graphene/nanowires UV LEDs

CrayoNano is about to revamp the UV LED industry with a technology based on a unique method of growing nanowires on graphene. Being transparent to all wavelengths, graphene represents the ideal substrate and transparent contact for ultraviolet light emitting diodes (UV LEDs). By growing AlGaN (aluminium gallium nitride) nanowires on graphene, graphene will be used both as a substrate and as a UV transparent electrode in order to achieve a high external efficiency. Nanowires on graphene enables critical improved internal quantum efficiency, operating lifetime, and reliability, especially for deep UV. The result is UV LEDs with 10 times higher efficiency at less than 10 % of the cost of existing deep UV LEDs. CrayoNano's unique device structure thus leads to reduced heat loss, and in addition reduced material consumption. Nanowires enables improved internal quantum efficiency, operating lifetime, and reliability. The result is a flexible and extremely thin and lightweight epiwafer able to emit large amounts of light from a small area. This significant improvement in efficiency, reduction in energy consumption and cost advantage will radically enable new applications and improve critical applications such as water and food processing disinfection, air purification and environmental monitoring and life science measurements. CrayoNano is working to shut the door on mercury arc lamps used for UV today and be the technology leader in a huge and fast-growing market.
