Abstract Nodal-line semimetals have become a research hot-spot due to their novel properties and great potential application in spin electronics. It is more challenging to find 2D nodal-line semimetals that can resist the spin-orbit coupling (SOC) effect. Here, we predict that 2D tetragonal ZnB is a nodal-line semimetal with great transport properties. There are two crossing bands centered on the $S$ point at the Fermi surface without SOC, which are mainly composed of the ${\rm p}_{xy}$ orbitals of Zn and B atoms and the ${\rm p}_{z}$ orbitals of the B atom. Therefore, the system presents a nodal line centered on the $S$ point in its Brillouin zone (BZ). And the nodal line is protected by the horizontal mirror symmetry $M_{z}$. We further examine the robustness of a nodal line under biaxial strain by applying up to $-4%$ in-plane compressive strain and 5% tensile strain on the ZnB monolayer, respectively. The transmission along the $a$ direction is significantly stronger than that along the $b$ direction in the conductive channel. The current in the $a$ direction is as high as 26.63 μA at 0.8 V, and that in the $b$ direction reaches 8.68 μA at 0.8 V. It is interesting that the transport characteristics of ZnB show the negative differential resistance (NDR) effect after 0.8 V along the $a (b)$ direction. The results provide an ideal platform for research of fundamental physics of 2D nodal-line fermions and nanoscale spintronics, as well as the design of new quantum devices.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
