Abstract:

The bias diffusion-limited aggregation model is used to study the growth of silver dendritic nanostructures in solution. In the simulation, right-angled isosceles triangle particles are introduced in twodimensional square grids and the sticking possibilities of different particle sides are introduced to describe the effect of the surfactant. Our simulation results show that the dendritic nanostructures become denser with increasing bias voltage. It is also found that the dendritic nanostructures become much more symmetrical and regular when the surfactant is applied. Furthermore, if the effect of the surfactant is strong enough and the bias voltage is small, the branches of the nanostructures are assembled into silver plates. Our simulation results are helpful to explain the experimental results qualitatively.
