On the bases of simple structural models and earlier proposed theory the esti-mates of energy gap widths, effective masses and character velocities in 2D sheets, nanoribbons and chains for 26 graphene-like AN B8-N. compounds are obtained. It is shown that the decoration of the nanoribbons and chains leads to the cardinal change of their electronic spectrum.

Analytical Expressions

Green’s function method is used to find the dispersion low for a monolayer (ML) placed be-tween two crystalline slabs. Weak- and strong-coupling regimes are considered in details. For the systems graphene, hBN – metallic ML – SiC polytypes analytical expressions for the ML electron effective masses are obtained. It is shown that the effective mass decreases with the increase of the SiC polytype energy gap.
