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

微led，尤其是RGB微led被认为是未来显示技术的圣杯。Porotech的使命是通过不断创新，将微型led引入大规模生产的商业市场。我们的微led产品基于独特的工艺和定制的多孔结构，在过去的两年里取得了令人兴奋的技术和商业突破，建立了优势地位。然而，到目前为止，实现必要的高效率、超细间距红色像素对整个行业来说都是一个挑战。波罗泰克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英军博士的推动下，Porotech团队将与塞巴斯蒂安·伍德博士领导的国家物理实验室电子与磁性材料团队，以及郝玲教授领导的量子材料与传感器团队合作，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备，旨在建立多孔模板上led器件级多层次结构和复杂时空行为的多维、多尺度视图。在这个项目结束时，我们的目标是建立一个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的质量。Porotech之前曾与NPL密切合作。2020年，通过M4R， Porotech与NPL的Rob Simpson合作，对多孔晶圆进行了热测量，从而更深入地了解了热行为，帮助我们即使在大流行期间也能继续进行研发。我们目前的合作项目可以为未来在微型led， AR，电力电子和量子技术方面的更大挑战带来创新的解决方案。

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.
