CuTe nanocrystals may be used as an alternative to noble metals for plasmonics but requires understanding of the atomic structure and the influence of defects. Here Willhammaret al. use electron tomography to reveal the distribution of vacancies in the nanocrystals and their effect on the optical properties.
