We have studied theoretically a polaron dispersion law in the GaN crystal and AlN/GaN/AlN double nanoscale heterostructure. Every type of polarization oscillation an electron interacts with is taken into account. Calculations are performed in the framework of infinite and finite band-gap models. We show that with the nanofilm thickness increase interface phonon contribution in the polaron energy decreases, while that of confined phonons gains in value. We present calculation results of a polaron dispersion law in the region $k PACS number(s): 63.20.Kr, 79.60.Jv
