Circularly Polarized Light on Graphene with Trigonal Warping

Öz:

In this article, we theoretically investigate the electronic band structure of monolayer graphene in the presence oftrigonal warping and photo-induced effects. The total Hamiltonian of the system has been written and the opticalabsorption of circularly polarized light for the high frequency regime have been modelled by the Haldaneinteraction. The relation between trigonal warp aspects and optical absorption of circularly polarized light has beenoverviewed through the model. Additionally, theoretically analyzed the versatile electronic properties of trigonalwarped-graphene under circularly polarized light. We have concluded that photo-induced effect which inducedcircularly polarized light leads to the opening of energy gap between valance and conduction bands while raiseselectron-hole asymmetry in the system.

Öz:

Bu makalede tek tabakalı grafenin elektronik bant yapısını üçgensel eğrilik ve foto-kaynaklı etkiler varlığında teorik olarak araştırdık. Sistemin toplam Hamiltoniyeni yazılmış ve yüksek frekans rejimi için dairesel polarize ışığın optik absorpsiyonu Haldane etkileşimi ile modellenmiştir. Üçgensel eğrilik bakış açısı ile dairesel polarize ışığın optik absorpsiyonu arasındaki ilişki model üzerinden genel olarak incelenmiştir. Ayrıca, dairesel polarize ışık altındaki üçgensel eğrilikli grafenin çok yönlü elektronik özelliklerini teorik analiz edildi. Dairesel polarize ışığı indükleyen foto-kaynaklı etkinin, sistemde elektron boşluk asimetrisi üretirken, valance ve iletken bantlar arasında enerji boşluğunun açılmasına yol açtığı sonucuna varıldı.
