Gaps in the spectrum of epitaxial graphene formed on …

Silicon carbide NH-SiC polytypes with N = 2, 4, 6, and 8 are considered as substrates for the epitaxial formation of graphene. The density of states for the substrates is described using the Haldane-Anderson model. It is shown that this model always leads to the appearance of two gaps in the graphene spectrum, which are adjacent to the valence and conduction bands of the substrate. The gap

Infrared: Appliion - Chemistry LibreTexts

Each band in a spectrum can be attributed to stretching or bending mode of a bond. Almost all the fundamental vibrations appear in the mid-infrared region. For instance, 4000 – 2500 cm -1 region usually can be assigned to stretching modes of O-H, N-H or C-H. Triple-bond stretching modes appear in the region of 2500 – 2000 cm -1 .
