The effect of the transmission coefficient on energy of graphene nanoribbons with two potential barrier

Low dimensional transmission coefficient as a main transport factor need to be explored in this work the transmission coefficient for multi potential barriers is investigated. Alltheoretical expressions such as height, width of potential barriers, distance between them and carrier property are included to have exact value of transmission coefficient. Additionally, as it is required in many electronic devices to specify conductance of component the exactdetermination of transmission coefficient especially for graphene based devices is analyzed. Non-isotropic character of transmission coefficient causes to have some extension on Land Auer formalism to derive more accurate expression on graphene based transistors. Finally based on the proposed model the temperature effect on device characteristics is discussed
