Spatiotemporal Imaging of Thickness-Induced Band Bending Junctions
Joeson Wong, Artur R. Davoyan, Bolin Liao +8
Van der Waals materials exhibit naturally passivated surfaces and can form versatile heterostructures, enabling observation of carrier transport mechanisms not seen in three-dimens…
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…
High-temporal-resolution electron microscopy for imaging ultrafast electron dynamics

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…
Real time observation of cuprates structural dynamics by Ultrafast Electron Crystallography
F. Carbone, N. Gedik, J. Lorenzana +1
The phonon-mediated attractive interaction between carriers leads to the Cooper pair formation in conventional superconductors. Despite decades of research, the glue holding Cooper…
Direct Role of Structural Dynamics in Electron-Lattice Coupling of Superconducting Cuprates
F. Carbone, D. -S. Yang, E. Giannini +1
The mechanism of electron pairing in high-temperature superconductors is still the subject of intense debate. Here, we provide direct evidence of the role of structural dynamics, w…
