Thermoelectrical properties of Bi2Te3 nanocomposites

Materials Today: Proceedings, 2019
Abstract Bi2Te3/graphite nanocomposite samples were prepared by mixing different weight percentage of graphite (x=0.0, 0.5 and 1.0) with Bi2Te3 and then subsequently ball milled. XRD results indicate the solid state insolubility of graphite phases in Bi2Te3 as no shift was observed in the peaks corresponding to Bi2Te3 in the composite samples.

Physical Properties of Bi2Te3 Nanolayers

2014
The properties of very thin Bi2Te3 (nano-) layers of different thickness prepared by pulsed laser deposition at different fluences are presented. Thermoelectric properties such as the thermal conductivity, the in-plain electrical conductivity, the Seebeck coefficient and also crystallinity, composition and morphology are presented.

Self-intercalation in Bi2Te3〈Cu〉

Inorganic Materials, 2008
We have studied the electronic properties of Bi2Te3〈Cu〉 crystals. The results indicate that, during natural growth and subsequent self-intercalation, copper layers are formed between Te(I)-Te(I) layers in the basal plane (0001). On cleaved (0001) surfaces, quasi-two-dimensional layers with islands were found.

The crystal structure of Bi2Te3−xSex

Journal of Physics and Chemistry of Solids, 1963
Abstract It has been confirmed that Bi 2 Te 3 and Bi 2 Se 3 form complete solid solutions, their space group being D 5 3d - R 3 m . The unit cell dimensions for the specimens having various compositions are given. The atomic parameters are found to be u = 0.4000 and v = 0.2097 for Bi 2 Te 3 , u = 0.3958 and v = 0.2118 for Bi 2 Te 2 Se ...

Influence of Bi2Te3 substrates with different microstructures on the thermal stability and kinetics of Ni/Bi2Te3 joints

Applied Surface Science
Thermoelectric technology enables direct conversion between thermal and electrical energy, and the long-term reliability of its devices depends on the stability of the interface between the thermoelectric legs and the metal electrodes. Bi2Te3-based alloys are thermoelectric materials for near-room-temperature applications, and Ni is often used as a ...
