In this work, nano capacitors simulated with carbon nano tubes (CNT) electrodes anddielectric nano tubes of Boron Nitride. Four configurations Studied consist of(3,3)(6,6)(13,13),(4,4)(8,8)(14,14),(5,5)(10,10)(15,15),(6,6)(12,12)(17,17). Total charge electric,the potential difference, dielectric constant and capacity for capacitors calculated. In this work,the simulation of nano capcitor studied with carbon nanotube electrodes and Boron Nitride nanotube dielectric. The calculations were performed using Gaussian 09 soft ware and the method ofDFT and semi empirical method and chelpg, extended-huckel commands. Nano tube modelersoft ware is used to simulate the nano capacitor. The values of the electric charge have beenobtained from the Δq=∑q(out - q(in) equation. The potential difference has been obtained fromΔ∑(V(out - V(in)) equation. (Out) means external electrode and (in) means internal electrode.The following equation was used to calculate the capacity, c=q/V. It has Farad unit. K isdielectric constant, that is ε=kε0Keyword: Capacitor, Boron Nitride Nano
