Abstract: Present work reports an elegant method to address the emergence of two Dirac cones in a non-hexagonal graphene allotrope S-graphene (SG). We have availed nearest neighbour tight binding (NNTB) model to validate the existence of two… read more here.

Abstract: Strain provides a degree of freedom for effectively tailoring the electronic and optical properties of two-dimensional (2D) materials. Here, we theoretically demonstrate that the shift of two Dirac points under the tensile strain in the… read more here.

DOI: 10.1103/physrevlett.121.256402
Abstract: The merging or emergence of a pair of Dirac points may be classified according to whether the winding numbers which characterize them are opposite (+- scenario) or identical (++ scenario). From the touching point between… read more here.
