从石墨烯到TDMCs，拉曼光谱和拉曼成像在二维材料的表征和各种异质性的可视化中起到了非常重要的作用。此外尖端增强拉曼散射 (TERS) 和尖端增强光致发光 (TEPL)也广泛应用于进一步表征材料纳米尺度的结构、电子或形态异质性。
拉曼光谱在纳米尺度上二维材料的研发和表征具有什么优势？TERS在新型二维材料表征中是如何应用的？这些问题你将在本次讲座中找到答案。
11月17日12:00AM-1:00AM，HORIBA 将举办主题为纳米拉曼和PL在二维材料研究中的重要性（Raman and PL at the nanoscale: why it’s important for 2D materials）专题讲座。欢迎大家参加。

纳米拉曼和PL在二维材料研究中的重要性Raman and PL at the nanoscale: why it’s important for 2D materials
摘要
From graphene to TMDCs and beyond, Raman spectroscopy and Raman imaging proved to be extremely useful for characterization of 2D materials and visualization of various heterogeneities that occur naturally or are created on purpose. Quite often the scale of structural, electronic or morphological heterogeneity in these materials is on the order of a few tens of nanometres or less, which is beyond the spatial resolution of conventional Raman microscopy. Tip enhanced Raman scattering (TERS) and tip enhanced photoluminescence (TEPL) can address the problem of spatial resolution.
In this webinar we’ll demonstrate how TERS can enable Raman imaging of MXenes, a new class of 2D materials; probe number of nanoscale heterogeneities in 2D crystals: growth related, including lateral and vertical heterostructures, substrate induced, and the morphological heterogeneities that appear (intentionally or not) in the process of exfoliation/2D crystal transfer. Finally, we’ll discuss recent results on TERS imaging of reconstructed Moiré patterns in twisted bilayers of graphene.
