原位测量针尖增强近场拉曼光谱的一个孤立的单壁碳纳米管（SWNT）束已被证明通过施加单轴压力高达约2 GPa的束通过金属涂层的原子力显微镜针尖。我们研究了拉曼频率的压力依赖性和径向呼吸模式带的强度，D-带和G-带，这与单壁碳纳米管的变形所造成的尖端压力。
In situ measurement of tip-enhanced near-field Raman spectra of an isolated single-wall carbon nanotube (SWNT) bundle has been demonstrated by applying a uniaxial pressure up to approximately 2 GPa to the bundle via a metal-coated atomic force microscope tip. We investigated the pressure dependences of Raman frequencies and the intensity of the radial breathing mode bands, the D-band and the G-band, which were related to deformation of SWNTs caused by the tip pressure.
