Band functionalization

One outstanding material for this purpose is hexagonal boron nitride ( h- BN) [ 92- 98]. h- BN is an insulating isomorph of graphite ( Figure 5 a), a layered dielectric material with a wide band gap of ~ 5. 97 eV and a dielectric constant of ~ 4. In addition, the InBiCH 3 on h- BN sheet is observed to support a nontrivial large gap QSH, which harbors the edge states lying within the band gap of h- BN sheet.
