Abstract :
Summary form only given. Optically-excited terahertz (THz) radiation from unbiased semiconductors have been an important field of ultrafast optoelectronics since its discovery a few years ago. In this work, we report for the first time measurement of THz radiation from unbiased, as-implanted and post-annealed GaAs:As+ samples. The effect of thermal annealing time on depletion field, effective carrier mobility, as well as the peak THz radiating frequency of unbiased GaAs:As+ are investigated
