RESONANCE RAMAN SPECTROSCOPY OF CARBON NANOTUBES

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 可调谐激发拉曼装置主要用于单壁碳纳米管的研究。我们的重点是单壁碳纳米管的直径和手性表征，单壁碳纳米管的长度表征，单个单壁碳纳米管中的应变。最近，我们开始了单原子层石墨烯的研究。我们的重点是使用拉曼光谱来表征石墨烯中的应变。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The tunable excitation Raman facility has been primarily used for studies of single wall carbon nanotube (SWNT) studies. We have focused on diameter and chirality characterization of a SWNT sample, length characterization of SWNTs, strains in individual SWNTs. Recently, we have started studies on single atomic layer graphene sheets. We are focusing on characterizing the strain in graphene using Raman spectroscopy.
