  • Abstract
    Quantum interference between single and two photon inter-band absorption processes can lead to injection of electrical currents in direct and indirect band gap semiconductors. When the optical excitation occurs through 100 fs optical pulses the transient electrical currents emit THz radiation that can be used as a probe of the ultrafast current dynamics.
