We report on the effect of sp3 hybridized carbon atoms in acene derivatives adsorbed on metal surfaces, namely decoupling the molecules from the supporting substrates. In particular, we have used a Ag(100) substrate and hydrogenated heptacene molecules, in which the longest conjugated segment ...
The XPS spectra are deconvoluted into two contributions, which are attributed to sp2- and sp3-hybridized atoms, respectively, separated by 0.9 eV, independent of atomic density. The sp3 hybridization content extracted from XPS is consistent with the atomic density derived from the plasmon energy in...
It is well known that there exist three carbon allotropes in natural materials, that is, graphite, diamond, and amorphous carbon, con- taining the sp2, sp3, and mixed sp2/sp3 hybridized carbon atoms2, respectively. In the past three decades, intensive theoretical and experimental efforts have...

The previously reported material, graphite (or graphene) from the University of Idaho Thermolyzed Asphalt Reaction (GUITAR) was initially mistaken for a graphite, as it has some physical and morphological similarities with sp2-hybridized carbon materials [18,19]. Those initial characterizations best ...
The ta-C film contains basically two types of carbon bonds namely sp2 and sp3. The sp2 is graphite like and sp3 is diamond like hybridized bonds. One of the most important factors is sp3/sp2 ratio of the film which controls film's fundamental physical properties such as film hardness, coef...
