Chains of Nanoscale Dipoles in Alternating Electric Fields

Resumo

The excitability (increase in the number of charges at the poles of nonpoint dipoles) in chains of nanoscale dipoles with varying moments in weak external alternating electric fields (at the level E = 10^–13–10^–4 V/m) at low frequencies Ω < 10⁵ Hz has been investigated numerically. It has been found that the level of charge excitations in such systems has a nonlinear dependence with a maximum on the radius (in the range r = 20–200 nm) of nanoscale dipoles. It is concluded that, in these ranges, the probability of self-assembling of single dipoles into the chains is increased.
