Annotation | There were investigated the thickness (d) dependences of thermoelectric (TE) parameters (concentration n, mobility , conductivity , Seebeck coefficient S, and thermoelectric power S2) for bismuth-doped n-PbTe nanostructures containing 2 at. % Bi grown from the vapor phase on glass-ceramic. Nonmonotonous change of d-dependences for the studied parameters was explained by the quantization of the energy spectrum of electron gas in quantum well of the glass-ceramic/n-PbTe:Bi structure. On the basis of this assumption for these structures the theoretical d-dependences of the corresponding TE parameters were built and compared with the experimental dependences. |
