Journal ArticleDOI
The Thermoelectric Properties of Bismuth Telluride
Ian T. Witting,Thomas C. Chasapis,Francesco Ricci,Matthew Peters,Nicholas A. Heinz,Geoffroy Hautier,G. Jeffrey Snyder +6 more
TL;DR: In this paper, the authors identify and quantify the key material properties that make Bi2Te3 such a good thermoelectric material, which can be used for benchmarking future improvements in Bi2TE3 or new replacement materials.
Journal ArticleDOI
Anisotropic galvanomagnetic and thermoelectric properties of n-type Bi2Te3 single crystal with the composition of a useful thermoelectric cooling material
TL;DR: In this article, a single crystal of n -type Bi 2 Te 2..85 Se 0.15 with the composition of a useful thermoelectric cooling material was grown by the Bridgman technique.
Journal ArticleDOI
Electrical and thermoelectrical properties of undoped Bi2Te3-Sb2Te3 and Bi2Te3-Sb2Te3-Sb2Se3 single crystals
TL;DR: In this article, the thermoelectric properties and Hall effects of a number of undoped Bi 2 Te 3 -Sb 2 Te3 pseudo-binary and Sb 2 Se 3 pseudo-ternary single crystal alloys grown by the Bridgman method were measured over the temperature range from 77 to 580 K. All of the alloys showed p -type extrinsic conduction and the analysis of the Seebeck coefficient and electrical conductivity indicated partial degeneracy at lower temperatures.
Journal ArticleDOI
Highly textured Bi2Te3-based materials for thermoelectric energy conversion
TL;DR: In this paper, two textured p-type Bi0.4Sb1.6Te3 samples were prepared using a powder metallurgy approach, with the c axis parallel to the pressing direction.
Journal ArticleDOI
Investigation of the Valence Band Structure of Thermoelectric (Bi1−xSbx)2Te3 Single Crystals
TL;DR: In this article, the authors used combined optical-spectroscopic and transport investigations to determine all relevant valence band data for the whole series of mixed crystals (Bi1−xSbx)2Te3 (0 ≦ x ≦ 1).

Nichtparabolizität des valenzbandes von Bi2Te3 gefolgert aus transporteigenschaften
M. Stordeur,W. Kühnberger +1 more
TL;DR: In this article, the galvanomagnetic and thermoelectric effects of p-Bi2Te3 are interpreted by a non-parabolic one-valence-band model with many-valley structure.
Journal ArticleDOI
Magnetothermal Resistance and Magnetothermoelectric Effects in Bismuth Telluride
TL;DR: In this paper, the magnetothermal resistance and magnetothermoelectric effects have been measured for samples of p-type and n-type Bi2 Te3 at 77°k.
Journal ArticleDOI
Anisotropie des seebeck‐koeffizienten, der lorenz‐zahl und des hall‐koeffizienten von halbleitern, verursacht durch anisotrop gemischte streuung
TL;DR: In this paper, the authors show that the Seebeck coefficients, the Lorenz number, and the Hall coefficients are anisotropic magnitudes in semiconducting crystals only under special conditions.

Study of orientation in polycrystalline Bismuth telluride alloys
H.J. Goldsmid,F.A. Underwood +1 more
TL;DR: In this paper, it was concluded that hot-pressing is preferable to cold-pressing in the production of sintered thermoelements in the case of Bi2Te3 and its alloys.
