معرفی
Dr. Xin Yi is a Research Fellow at Heriot-Watt University's School of Engineering & Physical Sciences, affiliated with the Institute of Photonics and Quantum Sciences. He holds a PhD in Electronic and Electrical Engineering from the University of Sheffield (2015–2020) and joined Heriot-Watt in 2020 as a Research Associate. His research focuses on developing next-generation quantum detectors, particularly avalanche photodiodes and single-photon avalanche diodes (SPADs) for short-wave infrared (SWIR) applications. Funded by the EPSRC, his work emphasizes semiconductor materials like AlAsSb, III-V compounds, and Ge-on-Si heterostructures to enhance detector performance in quantum technologies.
Research interests include impact ionization mechanisms, semiconductor characterization, and device fabrication. Key achievements include designing low-noise Ge-on-Si SPADs with record sensitivity and high-gain avalanche photodiodes for SWIR detection. Yi has received the EPSRC Quantum Technology Career Development Fellowship (2022) and contributed to over 20 peer-reviewed publications. He collaborates internationally and actively presents at conferences, showcasing advancements in quantum detectors and optoelectronic materials.
His work bridges theoretical modeling and experimental validation, targeting applications in quantum communication, sensing, and imaging. Grants and fellowships support his exploration of novel semiconductor materials and fabrication techniques to push the boundaries of SWIR detection beyond traditional silicon limitations.
