Materials at the nanoscale have zero specific heat
Specific heat theories of Debye’s phonons and Einstein’s atomic vibrations including modification thereof by Raman are modified by quantum mechanics to include zero specific heat at the nanoscale.

Quantum Mechanics Questions the Molecular Dynamics of Submicron Structures
In the 1950s, Metropolis and Teller pioneered molecular dynamics (MD) as a method to derive the thermodynamic and transport properties of bulk molecular liquids. Submicron ensembles comprising a few hundred atoms with periodic boundary conditions were used to derive the bulk liquid properties.
