In the absence of actual data on the electrostatic capacitance of a SWCNT bundle

of these dimensions, a coarse model was developed in [3] using the fi eld solver

FastCap [96]. It was observed that the SWCNTs completely surrounded by other

nanotubes had a very small electrostatic coupling capacitance to ground com-

pared to those CNTs along the edges of the bundle (three orders of magnitude

smaller). SWCNTs that are nearly completely surrounded had capacitance (to

ground) over an order of magnitude less than CNTs along the edges. Their con-

tribution to the total electrostatic capacitance can thus be neglected. The electro-

static capacitance ...
