Porotech is an emerging Gallium Nitride (GaN) material technology developer and a spin-out from the University of Cambridge. We develop commercial-quality epi-wafers using innovative porosification technology, enabling our customers to unleash the potential of GaN electronics and optoelectronics. By introducing nano-pores (10-50 nm) into epitaxial film (50nm-5µm) at wafer-scale (6, 8, 12 inches), the whole wafer's optical, mechanical, thermal and electrical properties become tuneable. In Nov 2020, Porotech launched the disruptive Native Red Epi-wafer (Red emission from InGaN-based epi-structure) for microLED applications. In May 2022, Porotech launched full colour MicroLED displays with DynamicPixelTuning (DPT) Technology, enabling a pixel's emission to be tune to any wavelength in the visible range using a simple drive scheme. So our platform technology based on porous GaN not only red-shifts the InGaN LED's emission, but also can dynamically tune its colours from red to blue.Through this project we will establish the correlation between the colour tuneability and microstructures in MQW LED built on porous wafers. This will accelerate development progress for more efficient microLED products, resulting in lower cost, reduced risk, and much higher manufacturing yield.This knowledge will be transformed into Porotech's competitive advantage over those companies that do not invest in fundamental understanding, and hence potentially afford us leadership in microLED market share. Our aim is to supply porous wafer materials for microLED with dominant advantages. By our collaboration, we believe NPL and Porotech will contribute significantly to the national economy, especially within the deep-tech sector.

Porotech 是一家新兴的氮化镓 (GaN) 材料技术开发商，是剑桥大学的衍生公司，我们利用创新的多孔化技术开发商业品质的外延晶圆，使我们的客户能够释放 GaN 电子和光电子的潜力。在晶圆级（6、8、12英寸）的外延膜（50nm-5μm）中引入纳米孔（10-50nm），整个晶圆的光学、机械、热和电性能变得可调。 2020 年 11 月，Porotech 推出了用于 microLED 应用的颠覆性原生红色外延晶圆（基于 InGaN 的外延结构的红色发射）。 2022 年 5 月，Porotech 推出了全彩 MicroLED 显示器。借助 DynamicPixelTuning (DPT) 技术，可以使用简单的驱动方案将像素的发射调整到可见光范围内的任何波长，因此我们的平台技术基于多孔。 GaN 不仅可以使 InGaN LED 的发射发生红移，还可以动态地将其颜色从红色调整为蓝色。通过这个项目，我们将建立基于多孔晶圆的 MQW LED 的颜色可调性和微结构之间的相关性，这将加快开发进度。以获得更高效的 microLED 产品，从而降低成本、降低风险并提高制造良率。这些知识将转化为 Porotech 相对于那些不投资于基础知识的公司的竞争优势，因此可能为我们提供帮助我们的目标是为 microLED 提供具有主导优势的多孔晶圆材料，我们相信 NPL 和 Porotech 将为国民经济，特别是在深科技领域做出重大贡献。
