© Published under licence by IOP Publishing Ltd.The current-voltage characteristic of a superlattice based on the semi-Dirac crystals has been studied. The case of the absence of a gap between valence and conduction mini-band has been considered. Such a superlattice has been shown to be characterized by both semi-metal and narrow-band semiconductor electrical properties. From the one hand there is the point in the Brillouin zone close to which the depletion of the states occurs without gap opening. From the other hand there is the portion of negative differential conductivity in the current-voltage characteristic. The dependences of longitudinal conductivity and maximum of the current-voltage characteristic on the Fermi energy have been investigated.
