Ratio of the specific heat of metallic nanofilms to the bulk value. The solid squares, circles, and triangles denote the results of the suspended Pt nanofilms measured in this work; the hollow symbols denote reference data for supported Cu, Al, and Au nanofilms (20–60-nm thick) with significant size effects (c_p,nanofilm/c_p,bulk > 1); spheres denote reference data for a supported Au nanofilm (54.6-nm thick) with no size effects (c_p,nanofilm/c_p,bulk = 1).
