Ultrafast formation of topological defects in a 2D charge density wave
Yun Cheng, Alfred Zong, Lijun Wu +13
Topological defects play a key role in nonequilibrium phase transitions, ranging from birth of the early universe to quantum critical behavior of ultracold atoms. In solids, transi…
Direct observation of ultrafast thermal and non-thermal lattice deformation of polycrystalline Aluminum film
Runze Li, Pengfei Zhu, Jie Chen +3
The dynamics of thermal and non-thermal lattice deformation of nanometer thick polycrystalline aluminum film has been studied by means of femtosecond (fs) time-resolved electron di…
Carrier emission of n-type Gallium Nitride illuminated by femtosecond laser pulses
Runze Li, Pengfei Zhu, Jie Chen +3
The carrier emission efficiency of light emitting diodes is of fundamental importance for many technological applications, including the performance of GaN and other semiconductor…
Investigation of transient surface electric field induced by femtosecond laser irradiation of aluminum
Run-Ze Li, Pengfei Zhu, Long Chen +5
Transient surface electric fields induced by femtosecond laser irradiation of an aluminum film were investigated directly by ultrashort electron pulses. At pump intensities of 2.9~…
Simultaneous Investigation of Ultrafast Structural Dynamics and Transient Electric Field by Sub-picosecond Electron Pulses
Run-Ze Li, Pengfei Zhu, Long Chen +4
The ultrafast structure dynamics and surface transient electric field, which are concurrently induced by laser excited electrons of an aluminum nanofilm, have been investigated sim…
