Energy bands and transport phenomena among Graphene Nanostructures

The book presents a detailed study on GRAPHENE Nanoelectronics’. Comprehensive analyses of energy band structures and charge transport behaviors among various types of the Graphene based Nanostructures are presented. Especially, the Armchair (AC) and Zigzag (ZZ) shaped graphene nanoribbons (GNRs) have been used in nanodevices. Various approaches for tricky samples’ modeling are discussed in detail. The density of states, transmission spectra and current-voltage characteristics are examined for the Graphene nanodevices. The observance of transmission eigenstate conduction channels and strong couplings among various sections of the nano-device are also rightly elucidated, which helps in understanding of different modes of the charge transport. To finish with the work, a Z junction nanotransistor is simulated and the I-V characteristics are studied. Finally yet importantly, the book is very helpful in understanding the intrinsic properties of the Graphene based nanomaterials for futuristic Nanotechnology applications.
