The particle size dependence of cohesive energy of metallic nanoparticles

Based on the concept that the cohesive energy can be regarded as the required energy to separate the metallic crystal into individual atoms by destroying the metallic bonds, a method is developed in this letter to calculate the cohesive energy of metallic nanoparticles. The calculation predictions a...

Description
Summary:Based on the concept that the cohesive energy can be regarded as the required energy to separate the metallic crystal into individual atoms by destroying the metallic bonds, a method is developed in this letter to calculate the cohesive energy of metallic nanoparticles. The calculation predictions are consistent with the experimental values of Mo and W nanoparticles.
