Femtosecond electron imaging of defect-modulated phonon dynamics
Phonons—crystal lattice vibrations—interact with crystal defects on the nanometre spatial scale and femtosecond timescale. Here, the authors demonstrate direct, real-space imaging of the nucleation, emergence and dispersion of single-phonon wavefronts at individual atomic-scale defects in semiconduc...
