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是一款新兴的氮化炮（GAN）材料技术开发人员，也是剑桥大学的拆卸。我们使用创新的孔隙化技术开发商业质量的Epi-Wafers，使我们的客户能够释放GAN电子和光电子的潜力。通过将纳米pores（10-50 nm）引入摇摆尺度（6、8、12英寸）的外延膜（50nm-5µm）中，整个Waver的光学，机械，热和电气变得可调。 2020年11月，Porotech推出了用于微胶片应用的破坏性本机红色Epi-Wafer（基于Ingan的EPI结构的红色发射）。 2022年5月，Porotech使用DynamicCixelting（DPT）技术启动了全彩色微型显示器，使Pixel的发射能够使用简单的驱动方案调整到可见范围内的任何波长。因此，我们基于多孔gan的平台技术不仅是Ingan LED的排放量，而且可以将其从红色转变为蓝色。通过此项目，我们将在MQW LED中建立颜色的可调性与在多孔波的MQW LED中的相关性。这将加速开发进度，以获得更有效的微型产品，从而导致较低的成本，降低的风险和更高的制造业产量。与那些不投资基本理解的公司相比，这一知识将转变为Porotech的竞争优势，因此潜在地使我们在微覆盖市场份额方面具有领导能力。我们的目的是提供多孔的工资材料，以微覆盖优势。通过我们的合作，我们相信NPL和Porotech将对国民经济产生重大贡献，尤其是在深技术领域。
