We present a numerical investigation of terahertz channel plasmon polaritons (CPPs) propagating in a semiconductor InSb. It is shown that these CPPs can simultaneously exhibit subwavelength field confinement and relatively long propagation length. Moreover, single-mode propagation is available for terahertz CPPs in a certain frequency range.
