Visualization of Photocurrents in Nanoobjects by Ultrafast Low-Energy Electron Point-Projection Imaging

Not Accessible

Your library or personal account may give you access

Abstract

Ultrafast dynamics of photocurrents in semiconductor nanowires are investigated with femtosecond time and nanometer spatial resolution. We demonstrate the capability of time-resolved low-energy electron point-projection imaging as a novel tool for mapping transient fields at nanostructures.
