Electrical and thermoelectric properties of 90%Bi2Te3-5% Sb2Te3-5% Sb2Se3 single crystals doped with SbI3

Preferential orientation and thermoelectric properties of p-type Bi0.4Sb1.6Te3 system alloys by mechanical alloying and equal channel angular extrusion

“…Although single crystal materials present excellent thermoelectric properties, they are easily fractured due to weak Van der Waals bonding between the Te (1) -Te (1) layers [2,3]. One available approach for improving mechanical properties is to prepare polycrystalline materials by powder metallurgy technology [4][5][6] such as pulverized and intermixed elements sintering (PIES), mechanical alloying (MA), hot pressing (HP). Although the mechanical * Corresponding author.…”

Microstructure and thermoelectric properties of n-type Bi2Te2.85Se0.15 prepared by mechanical alloying and plasma activated sintering

“…Currently, unidirectional crystal growth methods such as zone melting or Bridgman technology [3,4] are widely used for preparing these alloys. Although, the resulting single crystal materials present excellent thermoelectric properties, they have poor mechanical property due to weak Van der Waals bonding between Te (1) -Te (1) layers and coarse grain size [5,6].…”

Thermoelectric Performance of Micro/Nano-Structured Bismuth-Antimony-Telluride Bulk from Low Cost Mechanical Alloying

“…Different synthesis methods have been explored with different compositions for achieving a high thermoelectric performance [2,6]. The bismuth-antimony-telluride (Bi-Sb-Te) alloys are traditionally prepared by crystal growth methods such as Bridgman technology or Zone melting [7,8].…”
