摘要：

A new metallic 2D material with high electrical conductivity (1×103 S m-1) consists of VSe2 ultrathin nanosheets with 4-8 Se-V-Se atomic layers. This is the first 2D transition-metal dichalcogenide with intrinsic room-temperature ferromagnetism. The nanosheets increase the charge-density-wave transition temperature to 135 K by dimensional reduction. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
