Abstract
The dependence of the interwall conductance on distance between walls and relative positions of walls are calculated at the low voltage by Bardeen method for ( n , n ) @ ( 2 n , 2 n ) double-walled carbon nanotubes (DWCNTs) with n = 5 , 6 , … , 10 . The calculations show that interwall conductance does not depend on temperature (for T ⩽ 500 K ) and current-voltage characteristic is linear. The conductance decreases by 6 orders of magnitude when the interwall distance is doubled. Thus, depending on the interwall distance, DWCNTs can be used as temperature stable nanoresistors or nanocapacitors.
