Preparation and properties of P-type Bi2Te3-based materials with high preferred orientation

Fenmo yejin jishu
Using the Bi0.4Sb1.6Te3+3%Te (mass fraction) melting crystal rods as the raw materials, the alloy ingots with good orientation were prepared by water-cooled copper crucible maglev melting technology. The P-type Bi2Te3-based alloy powders were obtained by

Synthesis and thermoelectric characterization of Bi2Te3 nanoparticles

, 2009
We report a novel synthesis for near monodisperse, sub-10-nm Bi2Te3 nanoparticles. At first, a new reduction route to bismuth nanoparticles is described which are applied as starting materials in the formation of rhombohedral Bi2Te3 nanoparticles.
