The paper reports the observation of low-energy Van Hove singularities (VHSs) in twisted graphene layers, which are seen as two pronounced peaks in the density of states (DOS) measured by scanning tunneling spectroscopy (STS). The VHSs are generated by rotating stacked graphene layers, allowing the Fermi energy to be brought arbitrarily close to the VHSs by varying the rotation angle. This phenomenon opens new possibilities for engineering electronic phases in graphene, such as charge-density waves (CDWs) and superconductivity. The study demonstrates that the VHSs are robust and can be controlled by the angle of rotation, providing a powerful tool for manipulating electronic properties in graphene. The findings highlight the unique properties of graphene, where the position of the Fermi energy and VHSs can be tuned, unlike in most other materials.The paper reports the observation of low-energy Van Hove singularities (VHSs) in twisted graphene layers, which are seen as two pronounced peaks in the density of states (DOS) measured by scanning tunneling spectroscopy (STS).
