Abstract The commensurate charge density wave (CCDW) phase in 1T-TaS2 is a prototypical correlated state tied to diverse emergent quantum phenomena. However, its stability is intrinsically limited to cryogenic temperatures. Tailoring correlated electronic states and stabilizing the CCDW phase at room temperature offer new opportunities to investigate and control emergent phenomena under ambient conditions.

Abstract Two-dimensional atomic crystals (2DACs), which feature non-bonding van der Waals (vdW) gaps between crystalline atomic layers, allow selected atoms or molecules to intercalate. When confined within these vdW gaps, the intercalants can self-assemble into ordered interlayers between adjacent 2D atomic lattices, forming well-defined intercalated superlattices.

Abstract Tailoring magnetic ordering in solid-state materials is essential for emerging spintronics1,2. However, substitutional lattice doping in magnetic semiconductors is often constrained by the low solubility of magnetic elements3,4,5, limiting the maximum achievable doping concentration (for example, less than 5%) and ferromagnetic ordering temperature6.
