  • Abstract
    Terahertz emission by ultrafast laser excitation of semiconductors is done conventionally in bulk wafers or thin films thicker than the optical penetration depth. Here we present counter-intuitive-results where enhanced terahertz emission is made possible by using ultrathin films of semiconductors.
