HIGHLIGHTS
- who: Giovanni M. Vanacore and collaborators from the Laboratory, USA Huazhong University have published the article: Ultrafast atomic-scale visualization of acoustic phonons generated by optically excited quantum dots, in the Journal: (JOURNAL) of 28/07/2017
- what: In Fig 3, the authors report the observed temporal change of the diffraction intensity for the Bragg spot, which is related to the dynamics within the dots.
- how: Because the optical excitation used in the work is 1.55 eV which is larger than the band gap of 1.8 eV for the AlGaAs substrate . . .
