It is intriguing that a solid containing ∼10 1 atoms of Ga or IV-A elements (C, Si, Ge, Sn, and Pb) melts at temperatures that are higher than the melting point of the corresponding bulk solid (T m,b ) though the T m of a solid in the 10 0-2 nm size range drops universally with the sample size. Consistent insight into the phenomenon of T m oscillation (suppression followed by elevation as the solid size is reduced from bulk to subnanometre size) over the whole range of sizes remains adoi:10.1088/0957-4484/16/8/051 fatcat:h2e3dntovnbtlitupjrmr7ggp4
