There are three widely used techniques for generating terahertz pulses, all based on ultrashort pulses from titanium-sapphire lasers or mode-locked fiber lasers. When an ultra-short (100 femtoseconds or shorter) optical pulse illuminates a semiconductor and its wavelength (energy) is above the energy band-gap of the material, it photogenerates mobile carriers. Most carriers are generated near the surface of the material (typically within 1 microme… WebbCu or Cu/Au (80nm thick Cu, 50nm thick Au) sputtered on Si were kept at 25 °C for a week or annealed at a temperature from 80 to 300 °C, then tested for THz emission under femtosecond laser irradiation (35 fs-800nm). THz radiation was detected from samples annealed from 80 to 170 °C, which had a Cu2O/Cu interface as the THz source.
