Zigzag $C_{2}N$ Nanoribbions under Edge Modifications as Multi-functional Spin Devices

Abstract

Recently, a holely two-dimensional (2D) $C_{2}N$ crystal with the wide band gap has been successfully synthesized. However, its non-magnetic property largely limits real applications in spintronics. Here we find that the edge magnetism can be introduced by tailoring the holely 2D $C_{2}N$ crystal into nanoribbons with zigzag edges. When edge N atoms are bare or passivated by H atoms, the device can be used to design high-performance thermospin device and thermal rectifier. This is ascribed to the emergence of a spin semiconducting property with the wide band gap. Moreover, if the edge N atoms are passivated by O atoms, the device shows a half-metallic property, meanwhile an obvious spin Seebeck effect can also be observed when a temperature difference is applied across the device.
