  • Abstract
    We present characteristics of THz radiation from GaAs wafers with metallic nano-dot arrays under optical excitation. Periodic arrays of metallic nano-dots were introduced by a nano-imprinting technique. We found that the metallic nano-dot arrays can make the bandwidth of THz radiation from GaAs surfaces narrow.
