Permanent polarization of small metallic particles
Abstract
Electric charge density in a metallic nanoparticle fluctuates due to inhomogeneities of various kinds. While in the bulk these fluctuations are compensated via Thomas--Fermi screening, residual surface charges give rise to a permanent electric dipole moment. We show that this dipole moment increases linearly with particle size, and fluctuates strongly from particle to particle
