Size and Shape Dependence on Melting Temperature of Gallium Nitride Nanoparticles

الملخص EN

The study of variation of the size and shape effect on the melting property of gallium nitride nanoparticles with their spherical and cylindrical geometrical feature is theoretically explored.

A numerical thermodynamical model has been devoted for the study.

A comparative investigation is made between the two shapes, at the range of ~3 nm dia.

The cylindrical GaN nanoparticles, whose melting point has been reported to decrease with decreasing particle radius, become larger than spherical-shaped nanoparticles.

The melting temperature obtained in the present study is in line with the function of radius of curvature.
