Abstract
The magnetic and electronic properties ofMoS2 nanoribbons with zigzag and armchair edges are investigated using LSDA-DFT.We found that the properties of the nanoribbons are very different from bulkMoS2 due to edge states. Armchair nanoribbons could be metallic and exhibit a magneticmoment; however, when passivating with hydrogen, they become semiconducting. Zigzagnanoribbons are metallic and exhibit unusual magnetic properties regardless ofpassivation. Our results could explain the recent evidence of ferromagnetism in flatMoS2 clusters, and motivatethe synthesis of novel MoS2 nanosystems.
