ABSTRACT

An approach for the calculation of thin film nucleation rate, J is highlighted in this

paper. Nucleation is a random process in which the number of nuclei formed in a fixed

interval of time is a random quantity and subjected to statistical laws. This normally

applies to either the frequency of appearance at time, t of nuclei per unit volume or area

of the system under consideration, based on the classical kinetic theory of nucleation. In

this work, the nucleation rates, J was calculated using a visual basic programming by

identifying appropriate parameters from the pre-exponential factor, contact angle,

desorption energy, diffusion energy, supersaturation ratio, etc.) and performing trial and

error execution. It was observed that, from the different plots of nucleation rates, J for

vapour/liquid and liquid/solid transition was found to lie within the reasonable

experimental ranges.
