Nanosized tin whiskers and spheres 15 nm in diameter form on anodic aluminum oxide (AAO) templates via a two-step anodization. The driving force, residual stress released from the template at a high temperature, causes tin whiskers of uniform size to grow on AAO within a few minutes. Various thicknesses AAO templates of in nano channels were fabricated from high-purity aluminum metals. The formation of hexagonal pores on aluminum was elucidated with reference to the equilibrium surface tension at each anodic condition. During a faster heating and cooling rate, tin formed coarser whiskers on the AAO, compared with fine nanowhiskers, which prefer slower rates of tempering. A series of scanning electron microscopy (SEM) images under various conditions of fabrication are introduced. Hence, the transformation of tin whiskers to a spherical shape is presented in detail in this study as well.
