It remains a significant challenge to have a unique spectroscopy that can study the charge carrier dynamics in in-situ optoelectronic devices with an ultrafast time resolution when optoelectronic devices are at work. Those devices include solar cells, photoconductors, LEDs, etc. The fundamental understanding of charge carrier dynamics not only is a central topic in basic fields in physics, chemistry, and materials science, but also it has a profound impact in photonics, optoelectronics, optical quantum communication, etc. For instance, the fundamental dynamics understanding will lead to the development of a new generation of technologies such as highly efficient and low-cost photovoltaics, and low-noise and sensitive single-photon detection. Thus, my long-term vision is to understand the charge carrier dynamics in advanced materials, leading to a new generation of device application in renewable energy and optical quantum communication. For the past five years, my previous group has addressed above challenge by developing a transformative ultrafast photocurrent spectroscopy (UPCS) with a state-of-the-art ultrafast time resolution. Using this advanced UPCS, a diverse HQP population including five PhDs, one MSc, and ten undergraduate students in my previous group have made significant contributions in perovskite materials and novel device development. Those achievements have been demonstrated by HQP's publications in Nature Communications, JACS, Matter, JPCL, ACS Photonics, and HQP's career at top-ranking universities and industrial companies. The UPCS includes three components: high-speed optoelectronic devices, a high bandwidth sampling oscilloscope, and an ultrafast laser. While the fabrication equipment of high-speed optoelectronic devices is supported by my start-up fund, and my current lab has already been equipped with a high bandwidth sampling oscilloscope, however, at Brock University currently there is no ultrafast laser available to develop the UPCS. In this proposal, the requested fund is to acquire a picosecond ultrafast laser to continue my research programs. Each year, 9-11 HQP will be receiving training in my lab, and the ultrafast laser requested is foundational. Thus, the ultrafast laser is essential for my research program and for the timely completion of HQP projects. EQUIPMENT REQUESTED: SIRIUS picosecond ultrafast laser from RPMC Lasers, Inc

它仍然是一个重大的挑战，有一个独特的光谱，可以研究在原位光电器件的电荷载流子动力学与超快的时间分辨率时，光电器件在工作。这些器件包括太阳能电池、光电导体、LED等。对电荷载流子动力学的基本理解不仅是物理学、化学和材料科学基础领域的中心课题，而且对光子学、光电子学、光量子通信等领域产生深远影响。对基本动力学的理解将导致新一代技术的发展，例如高效和低成本的光化学，低噪声、灵敏的单光子探测。因此，我的长期愿景是了解先进材料中的电荷载流子动力学，从而在可再生能源和光量子通信中实现新一代器件应用。 在过去的五年里，我的前一个团队通过开发具有最先进的超快时间分辨率的变革性超快光电流光谱（UPCS）来解决上述挑战。使用这种先进的UPCS，包括五名博士，一名硕士和十名本科生在内的多元化HQP人群在我之前的小组中为钙钛矿材料和新型器件开发做出了重大贡献。这些成就已经通过HQP在Nature Communications，JACS，Matter，JPCL，ACS Photonics上的出版物以及HQP在顶级大学和工业公司的职业生涯来证明。UPCS包括三个组件：高速光电器件、高带宽采样示波器和超快激光器。虽然高速光电子器件的制造设备是由我的启动基金支持的，而且我目前的实验室已经配备了高带宽采样示波器，但是，在布洛克大学，目前还没有超快激光器可用于开发UPCS。在这个建议中，所要求的资金是获得一个皮秒超快激光器，以继续我的研究计划。每年，9-11 HQP都会在我的实验室接受培训，而超快激光器是基础。因此，超快激光对于我的研究计划和及时完成HQP项目至关重要。所需设备：RPMC Lasers，Inc.的SIRIUS皮秒超快激光器
