Size Effect On Evaporation Temperature Of Nanocrystals

摘要

Based on our model for size-dependent cohesive energy, the size-dependent evaporation temperature of nanocrystals has been modeled without any adjustable parameter. The model predicts a decrease of the evaporation temperature of nanocrystals with decreasing size. The model predictions are in good agreement with available experimental results for Ag, Au and PbS nanocrystals.
