摘要：
We report on the first principle calculations of photocarriers kinetics in a photoconductive antenna excited by an ultrashort optical laser pulse. The solution of non-equilibrium Boltzmann equation is used to derive the expression for the irradiated electric field. The analysis reveals the important role of non-uniform photocarrier distribution inside the active layer in the formation of the terahertz radiation from the emitter in both collinear and anti-collinear directions.
