Abstract

The preparation of 1D WS(2) and MoS(2) flexible nanoribbons by laser-induced unzipping of the nanotubes is reported. The nanoribbons are of high quality, uniform width, and devoid of surface contamination. The zig-zag edges in WS(2) nanoribbons give rise to ferromagnetism at room temperature.
