The Historically Black Colleges and Universities - Undergraduate Program (HBCU-UP) provides support to strengthen STEM undergraduate education and research at HBCUs. This Equipment Proposal from North Carolina Central University (NCCU) seeks the establishment of an ultrafast fiber laser system to support materials research and education across STEM disciplines. The system will enable enhancement of existing ultrafast microscopy capabilities and development of additional far- and near-field optical and THz spectroscopy facilities.This fiber-based laser is a robust turnkey system that is resistant to changes in ambient laboratory conditions, minimizing the time and expertise needed for optimization and enabling experiments performed over longer durations and has sufficient power to enable simultaneous performance of several ultrafast spectroscopy experiments. These capabilities will be used to build time resolved transient absorption microscopy, photoluminescence microscopy, far- and near-field terahertz spectroscopy and two-dimensional electronic spectroscopy experiments to study carrier dynamics and charge transfer with ultrafast (~ 100 femtosecond) time resolution. The instrument will thus enable a diverse group of faculty and students drawn from the Chemistry and Physics programs at North Carolina Central University to investigate mechanisms underlying a wide range of ultrafast phenomena in advanced materials, including charge transport in heterogeneous organic-inorganic metal halide perovskites, charge transfer in mixed-dimensional 0D/2D heterostructures and the relationship between nanoscale structure and charge transfer in bulk polymer heterojunctions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

传统黑人学院和大学本科项目（HBCU-UP）为加强hbcu的STEM本科教育和研究提供支持。北卡罗来纳中央大学（NCCU）的设备提案寻求建立一个超快光纤激光系统，以支持STEM学科的材料研究和教育。该系统将增强现有的超快显微镜能力，并开发额外的远场和近场光学和太赫兹光谱设施。这种基于光纤的激光器是一种强大的交钥匙系统，可以抵抗实验室环境条件的变化，最大限度地减少优化所需的时间和专业知识，并使实验能够在更长的持续时间内进行，并且具有足够的功率，可以同时进行多个超快光谱实验。这些能力将用于建立时间分辨瞬态吸收显微镜、光致发光显微镜、远场和近场太赫兹光谱和二维电子光谱实验，以超快（~ 100飞秒）时间分辨率研究载流子动力学和电荷转移。因此，该仪器将使来自北卡罗来纳中央大学化学和物理专业的各种教职员工和学生能够研究先进材料中各种超快现象的机制，包括非均相有机-无机金属卤化物钙钛矿中的电荷传输，混合维0D/2D异质结构中的电荷转移以及纳米级结构与大块聚合物异质结中电荷转移之间的关系。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
