Abstract<\/h3>\n

We examine the congruent vaporization of ZnO islands using in\u00a0situ<\/i> transmission electron microscopy. Correlating quantitative measurements with a theoretical model offers a comprehensive understanding of the equilibrium conditions of the system, including equilibrium vapor pressure and surface free energy. Interestingly, the surface energy depends on temperature, presumably due to a charged surface at our specific condition of low P<\/span><\/span><\/span><\/span><\/span><\/span> and high T<\/span><\/span><\/span><\/span><\/span><\/span>. We find that the vaporization temperature decreases with decreasing system size, a trend that is more pronounced at higher T<\/span><\/span><\/span><\/span><\/span><\/span>. Applying our results of island decay towards the growth of the ZnO provides new insights into the cooperative facet growth of anisotropic nanocrystals.<\/p>\n","protected":false},"excerpt":{"rendered":"
