Ultrafast charge carrier dynamics in semiconductoring materials ultimately determine the performance of photoconductive terahertz (THz) emitters and receivers. Ion implantation of III-V semiconductors allows carrier dynamics to be tailored for a particular application, and thus the technique is increasingly being applied to the development of advanced materials for terahertz photonics. In this talk I will briefly introduce the technique of ion implantation and review some recent applications in THz photonics. I will then present time resolved conductivity studies of GaAs:As+, InGaAs:Fe+, InP:O+ and InP:Fe+ and relate these results to improved terahertz emitter and detector performance.
