The band gaps of these three structures are calculated to be 0.86, 4.94, and 0.97 eV, respectively, which are consistent with previously reported works [8, 37, 38].The band structure near the conduction band minimum (CBM) and valence band maximum … WebPhonon polaritons in monolayer hBN are confined in a volume about one million times smaller than the free-space photons. Both the polariton dispersion and their wavelength–thickness scaling law are altered compared to those of hBN bulk counterparts. These changes are attributed to phonon hardening in monolayer-thick crystals.
