Abstract: The unexplored terahertz(THz)region involves important phenomena of both fundamental and applied natures.Examples include phonon interactions,rotational transitions and intermolecular dynamics.Frequency tunable high power THz wave generation has been successfully achieved utilizing lattice resonance of LiNbO3 and GaP crystals,respectively.Semiconductor devices utilizing electron tunneling effect have also been developed.

Key words: THz wave generation, phonon interaction, semiconductor device,
