A Numerical Model for Determination of Electrostatic Charge Distribution on Conducting Nanowires

In this paper charge distribution in conducting nanowires and nanotubes has been studied theoretically. The proposed model is based on classical electrostatics. This numerical model overcomes the problem of dealing with different kinds of applied electric fields and nanowire geometries. Charge distribution is obtained by dividing the nanowire into smaller elements with a centre of effective electric charge. In this paper, different kinds of geometrical elements are investigated which are useful for straight and bent nanowires with different aspect ratios. Numerical results are presented for selected examples which are in good agreement with those of obtained by density functional theory in previous studies. The findings are useful for analysis of electromechanical systems.
