Effect of Indium doping on structural and thermoelec-tric properties of SnTe
Diptasikha Das, A. Jana, S. Mahakal +4
The solid state reaction method is employed to synthesize Sn1-xInxTe samples. Power Factors of synthesized samples are estimated from resistivity and thermopower data. Modification…
Concise overview of methods to enhance the thermoelectric efficiency of SnTe
Diptasikha Das, Kartick Malik
SnTe is a potential thermoelectric material in the mid temperature range. Detailed techniques to enhance the figure of merit by increasing the Power Factor, and reducing thermal co…

Pallabi Sardar, Suman Mahaka, Soumyadipta Pal +5
The most favorable structure of the synthesized TiCoSb half-Heusler alloy is explored theoretically and experimentally, and the best structure for thermoelectric conversion is repo…
Anomalous Power Factor Enhancement and Local Structural Transition in Ni-Doped TiCoSb
Suman Mahakal, Pallabi Sardar, Diptasikha Das +6
We report a significant enhancement (~269%) in the power factor (PF) and a local structural transition in Ni-doped TiCoSb samples (TiCo_{1-x}Ni_xSb, (x= 0.0, 0.01, 0.02, 0.03, 0.04…
Drastic modification in thermal conductivity of TiCoSb Half-Heusler alloy: Phonon engineering by lattice softening and ionic polarization
Suman Mahakal, Avijit Jana, Diptasikha Das +5
A drastic variation (~47%) in thermal conductivity (\k{appa}) for synthesized samples (TiCoSb1+x, x=0.0, 0.01, 0.02, 0.03, 0.04, and 0.06) is observed. The lowest \k{appa} is repor…
