Atomic force microscopy (AFM) is coupled with time-domain two-dimensional infrared (2DIR) spectroscopy to develop AFM-2DIR nanospectroscopy, which combines the spatial precision of AFM with the rich spectroscopic information provided by 2DIR spectroscopy. Application of this method reveals the anharmonicity of a carbonyl vibrational mode and the possible energy transfer pathways of hyperbolic phonon polaritons in isotope-rich hexagonal boron nitride.

二维红外光谱与原子力显微镜相结合


原子力显微镜 (AFM) 与时域二维红外 (2DIR) 光谱结合开发了 AFM-2DIR 纳米光谱，它将 AFM 的空间精度与 2DIR 光谱提供的丰富光谱信息结合在一起。该方法的应用揭示了富同位素六方氮化硼中羰基振动模式的非谐性以及双曲声子极化激元可能的能量传递途径。
