摘要：

The increase in the thermoelectric figure of merit in layered structures with quantum wells is calculated for the case of polar charge-carrier scattering by optical phonons. On the basis of previous and new calculations, it is concluded that the quantum confinement effect can give rise to the increase in the figure of merit only if the probability of carrier scattering decreases with increasing wave vector transfer.
