Piezoelectric measurement of multiple quantum well (MQW) on porous GaN wafer

微LED，特别是RGB微LED被认为是未来显示技术的圣杯。Porotech的使命是通过不断的创新，将MicroLED带入商业市场，实现大规模生产。我们的MicroLED产品基于独特的工艺和定制的多孔结构，在过去两年中取得了令人兴奋的技术和商业突破，确立了优势地位。然而，到目前为止，实现必要的高效率、超细间距的红色像素对整个行业来说是一个挑战。Porotech充分认识和理解科学在帮助经济增长和增加社会价值方面的作用。在联合创始人兼首席技术官刘迎军博士的倡导下，Porotech的团队将与NPL由Sebastian Wood博士领导的电磁材料团队，以及由凌浩教授领导的量子材料和传感器团队合作，通过A4I计划迎接挑战。该联盟配备了先进的扫描探针显微镜和非接触式微波谐振器系统等定制设施，旨在建立多维、多尺度的层级结构视图和设备级的复杂时空行为的多孔模板上的LED。到这个项目结束时，我们的目标是建立一种基于基本理解的计量方法，并最终满足制造要求，以开发、优化和确保我们的晶圆产品质量。Porotech之前曾与NPL密切合作。2020年，威盛M4R Porotech与NPL的Rob Simpson合作进行了多孔硅片的热测量，这使我们更深入地了解了热行为，帮助我们即使在流行病期间也能继续研发。我们目前的合作项目可以带来创新的解决方案，以应对未来在microLED、AR、电力电子和量子技术方面的更大挑战。

MicroLED, especially RGB microLED is considered as the holy grail of the future display technology. Porotech's mission is to bring microLED into commercial market at mass production scale through continuous innovation. Our microLED products based on unique process and customised porous structure have established advantageous position by achieving exciting technological and commercial breakthroughs in the past two years. However, until now, achieving the necessary high-efficiency, ultra-fine-pitch red pixels has proved a challenge for the whole industry.Porotech fully acknowledge and understand the role that science has in aiding economic growth and add value to society. Evangelized by Dr Yingjun Liu, co-founder and CTO, Porotech's team will partner with NPL's Electronic & Magnetic Materials Team led by Dr Sebastian Wood, and Quantum Materials and Sensors Team led by Prof Ling Hao to meet the challenge through A4I program. The consortium is well equipped with bespoke facilities such as advanced scanning probe microscopy and non-contact microwave resonator system, aiming to establish multiple dimensional, multiple-scale view of hierarchical structure and complex spatial-temporal behaviours at device level in LED-on-porous-template. By the end of this project, we aim to establish a metrological methodology based on fundamental understanding, and ultimately meet manufacturing requirements to develop, optimise and assure quality of our wafer products.Porotech has worked closely with NPL before. In 2020, via M4R Porotech worked with Rob Simpson from NPL for thermal measurement of porous wafer, which lead to deeper understanding of the thermal behaviours helping us to continue R&D even during pandemics. Our current collaborative project can lead to innovative solution on bigger challenges in the future on microLED, AR, power electronics, and quantum technology.
