“…In Fig 7 we compare our obtained specific-heat data at lower temperatures, both for HOPG and natural graphite, to abovementioned data of another HOPG sample [23], as well as to earlier published data below 1.9 K of a natural Madagascar graphite (NMG) by van der Hoeven, Jr. and Keesom [17], and of spectroscopic pure graphite powder by Mizutani et al [18]. The inset shows the same C p data from Refs.…”

“…We also include in Fig 8 theoretical calculations [24] Much discussion can be found in the literature [17,23,24] about the expected temperature dependence of the specific heat of pure carbon as a function of the dimensionality of the material, when going from 3D graphite to 2D graphene and to 1D single-walled nanotubes (SWNT). The main problem is to determine and understand the contribution of acoustic phonons to the specific heat.…”

“…29 In a later specific heat measurement on HOPG a value of 0.007 electron states/eV atom was obtained. 30 It should be pointed out that in our case we get the DOS for a surface graphene layer perturbed by alkali metal and this may certainly differ from the bulk DOS in graphite obtained from the specific heat measurements. Also, the value we obtain for n͑E F ͒ depends on the values used for the radius of the alkali metal atom.…”

“…Following recent bandstructure calculations, 7a ' 9a ' 22 we modified such a model by adding a step function of adjustable width W, and whose height is determined by the value of the density of states at the Fermi energy, /)(£>), as derived from specific-heat measurements. 23 The step, resulting from the enhancement of the density of states at the Fermi level upon intercalation, is a common feature of all the above calculations and has been ascribed to the hybridization of carbon and alkali-metal bands. 9a Accounting for disorder and phonon broadenings, we then convoluted that shape with a Gaussian broadening function to fit the data.…”
