Aspectos quirales del grafeno

the graphene, a carbon allotropy, is a success of the advances of the nanotechnology. being a nanostructure, this structural component of the graphite possesses properties that have transformed it into a potential substitute of the silicon in the design and production of integrated circuits. this article summarizes its origins, theoretical possibilities, as well as its practical properties. theoretical aspects of chirality in graphene are presented, specifically a chiral theory for graphene, linking born fedorov constitutive relations for an electromagnetic field with the wave functions of the chiral dirac equation for massless particles. as an application, some results on negative differential resistance are presented, important in the design of very high frequency oscillators.
