Abstract :
Device scaling of the electronic devices has brings the dominancy of quantum effect in nano-size device characterization. This paper presented the first band analytical model of the quantum capacitance for (16,0) zigzag graphene nanoscroll (ZGNS). The derivation of quantum capacitance is based on the differentiation of carrier density towards the Fermi energy. The Taylor´s series expansion is employed on parabolic energy band structure so that it can be modified in the form of Fermi Intergal. Owing to its unique geometry structure that provides high intercalation area, it is expected that ZGNS exhibit high quantum capacitance.
