Carrier Density Oscillation in photoexcited Semiconductors
Ebrahim Najafi, Amir Jafari, Bolin Liao +1
The perturbation of a semiconductor from the thermodynamic equilibrium often leads to the display of nonlinear dynamics and formation of spatiotemporal patterns due to the spontane…
Observation of a phonon avalanche in highly photoexcited hybrid perovskite single crystals
G. M. Vanacore, J. Hu, E. Baldini +11
In hybrid lead halide perovskites, the coupling between photogenerated charges and the ionic degrees of freedom plays a crucial role in defining the intrinsic limit of carrier mobi…
Spatial-Temporal Imaging of Anisotropic Photocarrier Dynamics in Black Phosphorus
Bolin Liao, Huan Zhao, Ebrahim Najafi +6
As an emerging single elemental layered material with a low symmetry in-plane crystal lattice, black phosphorus (BP) has attracted significant research interest owing to its unique…
Dynamics and control of gold-encapped gallium arsenide nanowires imaged by 4D electron microscopy
Bin Chen, Xuewen Fu, Jau Tang +4
Eutectic related reaction is a special chemical/physical reaction involving multiple phases, solid and liquid. Visualization of phase reaction of composite nanomaterials with high…
Dynamics of Photo-excited Hot Carriers in Hydrogenated Amorphous Silicon Imaged by 4D Electron Microscopy
Bolin Liao, Ebrahim Najafi, Heng Li +2
The dynamics of charge carriers in amorphous semiconductors fundamentally differ from those in crystalline semiconductors due to the lack of long-range order and the high defect de…
