摘要

在环境条件下对具有各种相关结构特征的石墨烯纳米泡进行了高空间分辨率尖端增强拉曼光谱(TERS)测量。考虑高分辨率TERS固有的特征特征,对得到的信号进行了分析。与平坦的石墨烯区域相比,纳米气泡及其相关的纳米凸钉钉位点显示出增强的TERS信号,这归因于强尖端增强电场与石墨烯中的面外变形之间的有效耦合。即使在没有缺陷的情况下,与高度受限的近场光的强耦合也会激活D波段,其强度取决于变形的程度。虽然在整个纳米气泡中观察到D波段,但与周围区域相比,一些局部区域表现出较弱的D波段强度。在高度受限的近场区域内,由于六边形晶格的数量有限,这种强度的降低很可能是由于缺陷导致六边形晶格缺失造成的。这些发现突出了近场诱导拉曼信号在环境条件下探测纳米材料高分辨率特征的能力,为其原位特性提供了更深入的了解。

Re-Examining Tip-Enhanced Raman Signals at High Spatial Resolution Under Ambient Conditions Using Graphene Nanobubbles.

High spatial resolution tip-enhanced Raman spectroscopy (TERS) measurements were carried out under ambient conditions on graphene nanobubbles with various associated structural features. The resulting signals were analyzed with consideration of the characteristic features inherent to high resolution TERS. Compared to flat graphene regions, nanobubbles and their associated nanoconvex pinning sites demonstrated enhanced TERS signals, attributed to the efficient coupling between the strong tip-enhanced electric field and out-of-plane deformations in graphene. Strong coupling with highly confined near-field light activates the D bands even in the absence of defects, with intensity depending on the degree of deformations. While the D band is observed across the nanobubbles, some local regions exhibit a weaker D band intensity compared to the surrounding areas. Given the finite number of hexagonal lattices within the area of highly confined near-field, this reduction in intensity is likely to result from defects that cause missing hexagonal lattices. These findings highlight the capability of near-field induced Raman signals in probing high resolution features of nanomaterials even under ambient conditions, providing deeper insights into their characteristics in situ.
