Particular features of the thermoelectric power factor of encapsulated structures formed by two-dimensional layers

Model approach is used to obtain expression for the thermoelectric power factor $\sigma S^2$ ($\sigma$ – 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 $S^2$ value on the chemical potential $\mu$ is examined. The analytical estimates of the function sigma $\sigma S^2(\mu)$ are given.
