李明杰博士帶領的跨學科團隊開發了具有增強多重激子效應的鹵化物鈣鈦礦納米晶體

多重激子效應是指半導體吸收一個光子而產生兩個甚至多個電子電洞對的過程,對於發展新型太陽能電池及高性能光電子器件至為重要。在光電轉換的過程中,如果光子的能量超過了電子電洞對所需的能量,多餘的能量會以熱能的形式消耗掉。如何能有效地利用熱耗散這部分能量來提高光電轉換效率並產生多重激子效應,是有待解決的難題。   最近,應用物理學系及光子技術研究院成員李明杰博士帶領的跨學科團隊開發了具有增強多重激子效應的鹵化物鈣鈦礦納米晶體。通過合理設計的納米晶體 (或稱為量子點) 能將高能光子轉化為多個電子電洞對,突破光電轉換效率的極限。更重要的是團隊首次證明了使用這種新設計的納米晶體,內部量子效率在低閾值下能超過 100%。 這項研究獲刊載於高影響力的科技期刊《Nature Photonics》。李博士的研究不單加深了人們對多重激子效應的認識,同時為開發高效能的光捕獲技術,例如光伏、光子探測和太陽能燃料生產等,提供了重要的參考依據。   請按此了解更多詳情 (只有英文版本)。

20220922 Prof Hao NSFC

郝建華教授團隊獲國家自然科學基金(NSFC)重點項目資助 (只有英文版本)

The Natural Science Foundation of China (NSFC) announced the application results of the 2022 Exercise in September 2022. Prof. Jianhua Hao’s project is successfully funded by the Key Program of NSFC. As PC/PI, Prof. Hao will collaborate the researchers in Nankai University and Sichuan Normal University, China to perform the study of multifunctional ultrathin ferroelectric integrated materials and devices towards neuromorphic computing and human visual system. Artificial intelligence is the frontier field with significant societal impact. However, the present technologies cannot sufficiently meet the needs of supporting the future information society in terms of information transmission bandwidth, power consumption, processing speed and intelligent control. Particularly, the rapid development of neuromorphic computing and artificial vision system urgently call for the innovation in multifunctional integrated materials and devices. On a basis of the Prof. Hao's internationally recognized works regarding ferroelectric manipulation of rare-earth-doped luminescence and ferroelectric optoelectronics, the proposed study is to effectively integrate ferroelectric polarization with multifunctional characteristics of electronic properties of semiconductor, photodetection and rare-earth ion luminescence. Novel synaptic devices with multi-modes will be demonstrated. The developed materials and devices in this project will provide potential solutions for overcoming the development bottleneck of information technology.   Refer to the News: https://mp.weixin.qq.com/s/rGTY0SaDL8Nlxr0oRnytxw

Prof Alan Pak Tao LAU 1

劉伯濤教授和中文大學研究團隊合作開發出最快的矽光子收發器 (只有英文版本)

Prof. Alan Pak Tao LAU, core member of PRI, and PolyU PhD student Xiong WU in collaboration with Prof. Hon Ki TSANG of CUHK developed the World’s fastest Germanium-Silicon(GeSi) on Silicon Photonics Transceiver at 216 Gb/s for Short-Reach Interconnects.   Abstracts For next generation highly integrated transceivers, silicon photonics (SiP) has attracted widespread interest in using mature CMOS production processes to manufacture high-yield, low-cost photonic integrated circuits (PIC) with the potential for integration with CMOS electronics. SiP now routinely integrate GeSi electroabsorption modulators (EAM) and GeSi waveguide photodiodes which have high responsivity and high bandwidth of over 65 GHz. Their ultra-compact dimensions make it possible for multi-channel transceivers to be realized on a small chip area. In this work, we joined forces with CUHK and combine our expertise in signal processing and device fabrication to demonstrate a world-record 216 Gb/s and 200 Gb/s over 1 km and  1.5 km fiber transmission respectively for GeSi-based modulators.   Please click HERE for more details.
