Sb concentration dependent Structural and Transport properties of Polycrystalline (Bi1-xSbx)2Te3 Mixed crystal
K. Malik, S. Mahakal, Diptasikha Das +3
(Bi1-xSbx)2Te3 (x=0.60, 0.65, 0.68, 0.70, 0.75 and 0.80) mixed crystals have been synthesized by solid state reaction. In depth structural, thermal, transport and electronic proper…
Tuning of thermoelectric properties with changing Se content in Sb2Te3
Diptasikha Das, K. Malik, A. K. Deb +7
Polycrystalline Sb 2 Te 3-x Se x (0.0 < x < 1.0) samples were synthesized by the solid state reaction method. The structural analysis showed that up to the maximal concentration of…
The effect of quenching from different temperatures on Bi 0.88 Sb 0.12 alloy
K. Malik, Diptasikha Das, S. K. Neogi +4
Structural, thermal, resistive and magnetic properties of melt quenched Bi 0.88 Sb 0.12 alloys are reported. The samples are heated at three different temperatures, followed by rap…
Defect induced structural and thermoelectric properties of Sb2Te3 alloy
Diptasikha Das, K. Malik, A. K. Deb +3
Structural and thermoelectric properties of metallic and semiconducting Sb2Te3 are reported. X-Ray diffraction and Raman spectroscopy studies reveal that semiconducting sample have…
Magnetoresistive property study of direct and indirect band gap thermoelectric Bi-Sb alloys
Diptasikha Das, K. Malik, S. Bandyopadhyay +3
We report magnetoresistive properties of direct and indirect band gap Bismuth-Antimony (Bi-Sb) alloys. Band gap increases with magnetic field. Large positive magnetoresistance (MR)…
Temperature-dependent structural property and power factor of n type thermoelectric Bi0.90Sb0.10 and Bi0.86Sb0.14 alloys
K. Malik, Diptasikha Das, S. Bandyopadhyay +4
Thermal variation of structural property, linear thermal expansion coefficient, resistivity, thermopower and power factor of polycrystalline Bi1-xSbx (x=0.10, 0.14) samples are rep…
