Query: Improvement in thermoelectric properties by tailoring at In and Te site
  in In2Te5   We study role of site substitutions at In and Te site in In2Te5 on the
thermoelectric behavior. Single crystals with compositions In2(Te1-xSex)5 (x =
0, 0.05, 0.10) and Fe0.05In1.95(Te0.90Se0.10)5 were prepared using modified
Bridgman-Stockbarger technique. Electrical and thermal transport properties of
these single crystals were measured in the temperature range 6 - 395 K. A
substantial decrease in thermal conductivity is observed in Fe substituted
samples attributed to the enhanced phonon point-defect scattering. Marked
enhancement in Seebeck coefficient S along with a concomitant suppression of
electrical resistivity \r{ho} is observed in Se substituted single crystals. An
overall enhancement of thermoelectric figure of merit (zT) by a factor of 310
is observed in single crystals of Fe0.05In1.95(Te0.90Se0.10)5 compared to the
parent In2Te5 single crystals.
