  • Abstract
    In lateral photo-Dember emitters pulses of coherent terahertz radiation can be generated by ultrafast above bandgap laser illumination of the surface of a partially metallic masked semiconductor. We investigate the role of the metallic mask and how the emission depends on spot size and fluence.
