| 中文摘要 | Ultrafast electron diffraction (UED) is a powerful technique for the measurement of transient structures. Employing our UED system, with its capability of detecting a sub-milli-Angstrom lattice spacing change with a sub-picosecond temporal resolution, we performed the real-time observation of both the coherent phonon and thermal lattice motions of polycrystalline 20 nm Al film, which was excited by femtosecond laser pulses. The obtained coherent oscillation period of similar to 7.4 ps and temperature rise of similar to 77 K agree well with those from theoretical calculation. This achievement offers great promise to conduct measurements of transient structures with atomic spatiotemporal resolution in many dynamical processes that can be initiated by ultrafast optical excitation. |
