Electrochemically Enabled Self‐Intercalation for Symmetry Breaking and Metallic Ferroelectricity in Nb 1+x S 2

ABSTRACT Two‐dimensional (2D) metallic materials that simultaneously exhibit inversion symmetry breaking are highly desirable for nonlinear optics, unconventional ferroelectrics, and symmetry‐driven electronic functionalities, yet controllably inducing structural asymmetry withou...

Gradient‐Mass‐Transfer Synthesis of 2D [Bi 2 CuO 3 ]SO 4 Crystals for Anisotropy Engineering

ABSTRACT The intrinsic physical anisotropy of low‐symmetry materials makes them highly promising candidates for polarization‐sensitive devices. However, their practical application remains constrained by the scarcity of single materials that can combine low symmetry with high per...

Observation of field-odd and field-free superconducting diode effects in $\mathrm{Mo}_{2}\mathrm{C}$ nanoflakes

Abstract The superconducting diode effect (SDE) enables nonreciprocal supercurrent flow, holding immense potential for ultra-low-power quantum electronics. Intrinsic SDE typically requires materials with inherent symmetry breakings. Here, we report the discovery of SDE in chemica...
