Surface Bonding Effect in Thermo Physical Properties of Aluminium Nitride Nano-Particle

Abstract

In this paper we have studied the size and number of atom-pairs dependence normalized per atom pair binding (cohesive) energy and melting temperature of the Aluminium nitride () nanoparticle using simple model approach. It is observed that the per-atom-pair binding (cohesive) energy and melting temperature are a quadratic function of the inverse of the particle size fornano-particle. The per atom-pair binding (cohesive) energy and melting temperature comes near that of their bulk value with increasing the particle size and same as the bulk material when the particle size is above than 100 nm.KeywordsSemiconductors; Size effect; Binding energy; Melting temperature; nanoparticle; nanocluster.
