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.

历史上的黑人学院和大学-本科生计划（HBCU-UP）为加强HBCUs的STEM本科教育和研究提供支持。来自北卡罗来纳州中央大学（NCCU）的设备提案寻求建立超快光纤激光系统，以支持STEM学科的材料研究和教育。该系统将能够增强现有的超快显微镜能力，并开发更多的远场和近场光学和太赫兹光谱设备。这种基于光纤的激光器是一个强大的交钥匙系统，能够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，并有足够的功率，使几个超快的同时进行。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，以研究载流子动力学和超快（~ 100飞秒）时间分辨率的电荷转移。因此，该仪器将使来自北卡罗来纳州中央大学化学和物理课程的各种教师和学生能够研究先进材料中各种超快现象的机制，包括异质有机-无机金属卤化物钙钛矿中的电荷传输，混合维0 D/二维异质结构和纳米结构之间的关系和电荷转移在大块聚合物异质结。这个奖项反映了NSF的法定使命，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。
