Abstract

Accurate prediction of the thermal stability of nanocrystals is of great significance for their synthesis, the design of multifunctional quantum devices, and the assessment of device service life. In this work, a theoretical model is established by introducing the solid-liquid interface energy γ_sl to describe the size-dependent melting temperature T_m(D) of nanocrystals. The model is validated against experimental and simulation data for diverse metal and semimetal nanocrystals, including Ni, Al, Sn, Au, Ag, Bi, Cu, Pd, In, and Pb. The results demonstrate that the proposed model provides more accurate predictions, thereby offering theoretical guidance for experimental synthesis and device design.
