TRANSPORT PHENOMENA IN GRAPHENE IN GENERALIZED LANDAUER – DATTA – LUNDSTROM MODEL
Journal Title: Сенсорна електроніка і мікросистемні технології - Year 2016, Vol 13, Issue 3
Abstract
On the basis of Landauer – Datta – Lundstrom transport model the following characteristics of graphene such as the density of electronic states and the carriers concentration dependence on gate voltage, the number of modes dependence on energy and maximum conductivity value, different mechanisms of carriers scattering in graphene, and the corresponding mobility in graphene determined through the Drude formula, the cyclotron frequency and the carriers effective mass in graphene, frequency limits for graphene FET, phonon density of states function, conductivity of p-n junction in the graphene channel, the relative contribution of electrons and phonons into the thermal conductivity of graphene, dependence of Seebeck coefficient in graphene on gate voltage are discussed in the tutorial article directed to serve researchers, university teachers and students. The article also presents a brief review of the development of a graphene physics, the references for the main works both theoretical and experimental in the field of graphene studies are presented. It is stressed, that the examination within the generalized Landauer – Datta – Lundstrom transport model enables the non-contradictory description of plentitude of physical phenomena in graphene, which obviously can not be described within a traditional approach, based on Drude model. The theoretical examination in the article is always followed with a comparison with available experimental data. It is demonstrated how graphene due to its unique physical characteristics permits to reveal relativistic effects, typical for a high energy physics in the ‘writing desk top’ experiments. Finally, the perspectives of the application of graphene and graphene-like materials in modern nanoelectronics devices are discussed.
