“…The fourth term, W im, em = eϕ i , is the additional electrostatic attraction, which is responsible for an increase in the electrostatic potential of an emitting particle in the field of an oppositely charged neighbor ing particle [16]. Actually, this term reflects the poten tial energy of an emitted electron in the field of the two particles.…”

The energy of pair interactions between metal nanoparticles of different sizes is shown to be able to increase upon coagulation due to the additional electrostatic effect resulting from mutual heteropolar charging of the particles. The tunnel electron transfer occurring upon the collisions between particles of dif ferent sizes may be the reason for the charging. The transfer is caused by the dependence of the electron work function on the particle size. The electron transfer through the interparticle gap equalizes the Fermi levels in particles of different sizes and is associated with this dependence. Using the example of bimodal silver nano colloids, it is shown that mutual heteropolar charging of particles with different sizes may accelerate the coag ulation of polydisperse colloidal systems by an order of magnitude or more as compared with monodisperse systems, in which this effect is absent.

A pseudopotential model of intergrain interaction in dusty plasmas is proposed to take into account both the electrostatic polarization and the screening phenomena. The derivation is entirely based on the renormalization theory of plasma particles interaction developed previously. Dust particles are assumed to be conductive such that the polarization phenomenon can strictly be treated in the charge-image approximation. Such an assumption imposes no restraint on generality of the present consideration because the polarization effects are essential for accurate description of intergrain interaction potential. The pseudopotential model is then used in the hypernetted chain approximation (HNC) for the dust component to obtain the radial distribution function which reveals the non-monotonic behavior at sufficiently large values of the dust coupling parameter. This can be viewed upon as a short-or even long-range order formation in the dust component of the plasma.
