Abstract :
A new unbiased terahertz photoconductive emitter is introduced. Unlike previous structures, this emitter does not require any external bias voltage. For photocarrier acceleration it rather makes use of the built-in electrostatic Schottky contact field formed at the electrode-photoconductor interface. A hybrid numerical simulation method is used to model and analyze this phenomenon.
