Soft X-ray spectro-ptychography on boron nitride nanotubes, carbon nanotubes and permalloy nanorods
Jaianth Vijayakumar, Hao Yuan, Nicolas Mille +6
Spectro-ptychography offers improved spatial resolution and additional phase spectral information relative to that provided by scanning transmission X-ray microscopes (STXM). Howev…
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…
Scanning Ultrafast Electron Microscopy: A Novel Technique to Probe Photocarrier Dynamics with High Spatial and Temporal Resolutions
Bolin Liao, Ebrahim Najafi
The dynamics of photo-excited charge carriers, particularly their transport and interactions with defects and interfaces, play an essential role in determining the performance of a…
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 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…
