Only recently, specially designed instrumentation for spatially-resolved electron energy-loss spectroscopy (EELS) has been developed to increase the attainable spectral resolution and the operating spectral range [1]. This progress has dramatically broadened the potential for applications of EELS for probing low-loss vibrational excitations. Pioneering experiments have demonstrated the capability of the fast electrons in Scanning Transmission Electron Microscopy (STEM) to probe vibrational fingerprints in organic samples [2], ionic crystals [3], and also in van der Waals materials [4].
