Webtransfer function of the recurrence relation (2). In the following section we develop the Prony and Pisarenko algorithms, based on (2), as constrained optimisation procedures for the same objective function, and prove that the parameter estimates derived from the Pisarenko are O(N 12) consistent. WebThe Pisarenko relation (thermopower versus carrier concentration) between the thermopower S and the hole concentration n in p-type PbTe at 300 K (full line). The points are data for Tl-doped PbTe. WebMar 7, 2024 · The Pisarenko relations for PbSe-PbS at 300 K and 850 K can be found in Figure S3. The solid lines in (c) are obtained from Klemens’ model. The solid lines in (d) are the calculated results based on (a–c). The calculation detail and the physical parameters for modeling (Table S3) can be found in the Supplementary material. try449
