Controllable dimensionality conversion between 1D and 2D CrCl₃ magnetic nanostructures.

ABSTRACT: The fabrication of one-dimensional (1D) magnetic systems on solid surfaces, although of high fundamental interest, has yet to be achieved for a crossover between two-dimensional (2D) magnetic layers and their associated 1D spin chain systems. In this study, we report the fabrication of 1D single-unit-cell-width CrCl₃ atomic wires and their stacked few-wire arrays on the surface of a van der Waals (vdW) superconductor NbSe₂. Scanning tunneling microscopy/spectroscopy and first-principles calculations jointly revealed that the single wire shows an antiferromagnetic large-bandgap semiconducting state in an unexplored structure different from the well-known 2D CrCl₃ phase.
