Model approach is used to obtain expression for the thermoelectric power factor sigma S2 (sigma - is the static conductivity, S - is the Seebeck coefficient), characterized monoatomic 2D layer of IV group elements, placed between two slabs, formed by hexagonal 2D layers of III-V com-pounds. The h-BN/graphene/h-BN structure is thoroughly studied and the dependence of the sigma S2 value on the chemical potential μ is examined. The analytical estimates of the function sigma S^2(μ) are given. Keywords: static conductivity, Seebeck coefficient, hexagonal monoatomic 2D layers.
