The vibrational excitations of nanostructures have been mapped using state-of-the-art electron microscopy. The results improve our understanding of these excitations, which will aid the design of nanostructures. See Letter p.529 The vibrational excitations of nanostructures have a fundamental effect on their suitability for various electronic, optical and thermal applications. Maureen Lagos and colleagues probe these excitations, using state-of-the-art electron microscopy to map the vibrational modes both at the surface and within the body of individual nanoparticles. Such information not only contributes to our knowledge of these fundamental vibrational modes, but will also be valuable for the design and optimization of nanostructures for practical use.
