Özet:

 


In this article, we theoretically investigate
the electronic band structure of monolayer graphene in the presence of trigonal
warping and photo-induced effects. The total Hamiltonian of the system has been
written and the optical absorption of circularly polarized light for the high
frequency regime have been modelled by the Haldane interaction. The relation
between trigonal warp aspects and optical absorption of circularly polarized
light has been overviewed through the model. The main aim of this investigation
is to assess the effects of trigonal warp and photo induced-effects which show
for the high frequency regime that the edge states can be controlled by tuning
the amplitude of the light. Additionally, theoretically analyzed the versatile
electronic properties of trigonal warped-graphene under circularly polarized
light. We conclude that photo-induced effect which induced circularly polarized
light leads to the opening of energy gap between valance and conduction bands
while raises electron-hole asymmetry in the system.
