Antimony telluride homologous superlattices with two to four antimonene layers exhibit a saddle point and associated van Hove singularity near the M-point, driven by Sb and Te pz orbital hybridization.

Nonlinear phonon dispersion in disordered solids emerges from a disorder-induced mesoscopic lengthscale that also controls wave attenuation, and both this softening and non-phononic modes contribute substantially to the boson peak in a disorder-strength-dependent way.
In the 2D attractive Hubbard model, Tc is enhanced near Van Hove singularities only for weak interactions, while the global maximum Tc occurs at intermediate coupling away from the singularity.

Nonlinear phonon dispersion in disordered solids and non-Debye vibrational spectra
Nonlinear phonon dispersion in disordered solids emerges from a disorder-induced mesoscopic lengthscale that also controls wave attenuation, and both this softening and non-phononic modes contribute substantially to the boson peak in a disorder-strength-dependent way.
