Abstract

The paper presents upper and lower limitations of nominal radius of liquid drops for rolling along an inclination by considering specified dimensionless Bond number, gravitational force, and Gibbs free energy. The relations between the Bond number and Gibbs free energy are established in this paper to determine the region of nominal radius of seeding droplets and the conditions of rolling mechanism. Experimental results show nanometer sized Co seeds formed on a patterned nonwettable silicon inverted pyramid {111} surface under the specified conditions will roll down and then aggregate in the bottom of the inverted pyramid to form a singular seed, which is applicable for 1-D material growth control.
