Abstract

Quantum transmission through a heterojunction formed by two types of nodal-line semimetals is investigated. Results show that the initial energy and energy range of the quantum transmission can be modulated efficiently when the barrier region demonstrates its different energy-band properties. Antiresonance points can also appear in the transmission function spectra. Moreover, if the barrier is parallel to the basal planes of the nodal-line semimetals, one gap appears in the transmission function spectrum instead of the normal antiresonance point. In addition, the Klein tunneling displays new characteristics in such a heterojunction. All these results provide useful information for adjusting the transmission behaviors in the heterojunctions of nodal-line semimetals.
