Xhmster 44 [extra Quality] -

Here we introduce , a new member of the TMC family that achieves a record‑high T_c of 44 K without external pressure or post‑synthetic doping. The material’s unique mixed‑valence Xh site (a combination of alkali‑metal and rare‑earth ions) provides intrinsic charge transfer to the transition‑metal selenide layers, stabilizing a high‑density of states at the Fermi level and enhancing electron‑phonon interactions.

The electronic band structure (Fig. 5a) shows multiple Ti‑derived d‑bands crossing the Fermi level, producing a high density of states N(E_F) ≈ 3.1 states eV⁻¹ f.u.⁻¹. Phonon dispersion (Fig. 5b) reveals a soft mode at the Γ point (Ω ≈ 12 meV) strongly coupled to electrons. The calculated electron‑phonon coupling constant and logarithmic average phonon frequency ω_log = 115 K give a McMillan‑Allen‑Dynes T_c ≈ 45 K (μ* = 0.10), in excellent agreement with experiment. Here we introduce , a new member of
