Ultrafast In-Plane Photo-Dember Ring at Buried Semiconductor Heterointerfaces Visualized by Scanning Ultrafast Electron Microscopy

Abstract The ultrafast transport dynamics of photogenerated carriers at buried semiconductor heterointerfaces govern the operation of modern optoelectronic devices, yet direct real-space visualization of in-plane carrier motion at such interfaces has remained an outstanding exper...
