Terahertz emission from lateral surge currents and suppression of dipoles under a metal mask

Terahertz emission from lateral surge currents and suppression of dipoles under a metal mask
Terahertz emission from lateral surge currents and suppression of dipoles under a metal mask
Pulsed broadband terahertz emission can be observed from lateral diffusion currents near the surface of a partially metallic masked semiconductor after ultrafast photoexcitation. We present a theoretical mechanism for the emission based on diffusion and dipole suppression under the metal mask with supporting experimental and theoretical evidence.

Abstract

Pulsed broadband terahertz emission can be observed from lateral diffusion currents near the surface of a partially metallic masked semiconductor after ultrafast photoexcitation. We present a theoretical mechanism for the emission based on diffusion and dipole suppression under the metal mask with supporting experimental and theoretical evidence.
