Abstract:
We have investigated the effect of Sb-deficiency on the thermoelectricfigure of merit (zT)ofZn4Sb3prepared by solid state reaction route. At high temperatures, the Seebeck coefficient (S) and electricalconductivity (σ) increases with increase in Sb deficiency whereas the thermal conductivity (κ) decreasesgiving rise to an increase in the overallzTvalue. The observations suggest that creation of vacanciescould be an effective route in improving the thermoelectric properties of Zn4Sb3system.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
