Van Hove Singularity - Wikipedia
A Van Hove singularity is a singularity (non-smooth point) in the density of states (DOS) of a crystalline solid.The wavevectors at which Van Hove singularities occur are often referred to as critical points of the Brillouin zone.For three-dimensional crystals, they take the form of kinks (where the density of states is not differentiable). ...
