Crystal defects affect the thermal and heat-transport properties of materials by scattering phonons and modifying phonon spectra 1 – 8 . To appreciate how imperfections in solids influence thermal conductivity and diffusivity, it is thus essential to understand phonon–defect interactions. Sophisticated theories are available to explore such interactions, but experimental validation is limited because most phonon-detecting spectroscopic methods do not reach the high spatial resolution needed to…

By demonstrating the excitation of both bulk and surface vibrational modes using a single probe, this work represents advances in the detection and visualization of spatially confined surface and bulk phonons in nanostructures.
Vibrational spectroscopy in the electron microscope
It is demonstrated that the vibrational signal has both high- and low-spatial-resolution components, that the first component can be used to map vibrational features at nanometre-level resolution, and that the second component can been used for analysis carried out with the beam positioned just outside the sample—that is, for ‘aloof’ spectroscopy that largely avoids radiation damage.

A classical response theory is developed that describes the interaction of fast electrons with (anisotropic) van der Waals slabs, revealing that the electron energy loss is dominated by excitation of hyperbolic phonon polaritons, and not of bulk phonons as often reported.
