Thermovoltage
WebbAs the data show, the contributions of the thermovoltage and the lead resistance to the observed signal can be separated by using the relation ΔU = A I bias + B, where the first term is due to the temperature-induced change in the lead resistance and the second one to the thermovoltage. Webb18 nov. 2024 · Polynickeltetrathiooxalate (poly[Ni-tto]) is an n-type semiconducting polymer having outstanding thermoelectric characteristics and exhibiting high stability under ambient conditions. However, its insolubility limits its use in organic electronics. This work is devoted to the production of a printable paste based on a poly[Ni-tto]/PVDF composite …

WebbMentioning: 4 - The thermoelectric response of HgTe quantum wells in the state of two-dimensional topological insulator (2D TI) has been studied experimentally. Ambipolar thermopower, typical for an electron-hole system, has been observed across the charge neutrality point, where the carrier type changes from electrons to holes according to the … Webbhibit a large thermovoltage. The resulting system was called a thermopile, because it was indeed a pile, made of a large heavy block. Figure 3 shows an original sketch of such an instrument after N. Nobili (1835). Due to the large thermal masses it was very slow in following signal changes. As can be imagined, these instruments were origi-
WebbHere, we employ thermovoltage measurements to GaSb/InAs core–shell nanowires, and reliably identify the dominant carrier type at room temperature as well as in the quantum transport regime at 4.2 K, even in cases where the conductance measurement does not allow for such a distinction. Webb5 jan. 2024 · The thermovoltage as a function of gate voltage showed 180° out-of-phase oscillations for the two cases of Φ = 0 and ± Φ 0 / 2, where Φ 0 is the magnetic flux quantum. The magnetothermovoltage oscillations also showed the 180° out-of-phase behavior at the local maximum and minimum locations in the gate-dependent oscillation …
