In this thesis, Dirac equation for different potential models in 2 space, 1-time dimension was studied. Physical applications of the low-dimensions Dirac equation are common. Graphene is a good example of this. Graphene is a two-dimensional layer of graffiti and draws interest in the fact that it is expected to be a suitable material for the development of electronic devices. Since Dirac electrons cannot be confined on the graphene due to the Klein paradox, it is suggested that the magnetic limitation be considered. With these studies, it has been concluded that massless charge carriers can be imprisoned with suitable electrical and magnetic barriers. However, different electrical and magnetic field configurations cause different results. In the presence of both electric and magnetic fields, analytical solutions of Dirac equations were obtained.
