Non-Technical Description:The acquisition of a tip-enhanced Raman spectroscope at San Jose State University (SJSU) can significantly improve our understanding of nanometer-scale materials and foster hands-on learning experiences for undergraduate and master's student researchers. The team at SJSU utilizes this optical instrument to tackle scientific challenges on materials science, with the materials for potential applications in transportation, energy storage, electronics, and health science. In addition, the instrument facilitates collaboration with external users in the area, including California State University - East Bay and the University of California - Merced. The acquisition also aims to advance high-quality public education for students, including those in underrepresented groups, thereby cultivating a highly trained and diverse science and engineering workforce in the United States.Technical Description:The acquired tip-enhanced Raman spectroscope integrates scanning probe microscopy and Raman spectroscopy, enabling scientists to determine molecular fingerprints and topography of nanomaterials down to 10 nanometer spatial resolution, which is a resolution level that could not be achieved using traditional optical measurement techniques. This combined analysis technique is also less invasive than some of the other techniques based on electron beams or X-rays, minimizing the sample damage and misinterpretation of the chemical and physical properties of nanomaterials. The researchers at SJSU apply this analysis technique to study quantum dot composites, biomaterials-driven interphase in batteries, quantum coherence properties in nanodiamonds, the effects of strain manipulation on transition metal dichalcogenide heterostructures, and the effects of surface dipole moments on nitrogen-vacancy centers for quantum sensing.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.

非技术描述：在圣何塞州立大学（SJSU）获得尖端增强拉曼光谱仪可以显着提高我们对纳米级材料的理解，并为本科生和硕士生研究人员培养实践学习经验。SJSU的团队利用这种光学仪器来应对材料科学的科学挑战，这些材料在运输，储能，电子和健康科学中具有潜在的应用。此外，该仪器还促进了与该地区外部用户的合作，包括加州州立大学东湾分校和加州大学默塞德分校。此次收购还旨在推进对学生的高质量公共教育，包括那些代表性不足的群体，从而在美国培养一支训练有素的多元化科学和工程人才队伍。技术说明：所收购的尖端增强型拉曼光谱仪集成了扫描探针显微镜和拉曼光谱，使科学家能够确定纳米材料的分子指纹和形貌，空间分辨率低至10纳米，这是使用传统光学测量技术无法达到的分辨率水平。这种组合分析技术也比基于电子束或X射线的其他一些技术侵入性更小，最大限度地减少了样品损坏和对纳米材料化学和物理性质的误解。SJSU的研究人员将这种分析技术应用于研究量子点复合材料，电池中的生物材料驱动界面，纳米金刚石中的量子相干特性，应变操纵对过渡金属二硫属化物异质结构的影响，以及表面偶极矩对氮的影响-该奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的学术价值和更广泛的影响审查标准。
