Title : Harvesting electricity using nanostructures


Enabling efficient thermoelectric materials with high thermoelectric figure of merit ZT = (S2σ/κ)T is the key to thermoelectrics research today, where S is the thermo-electric voltage, σ is the electrical conductivity, κ the thermal conductivity and T the temperature. Thermoelectricity is among the cleanest form of energy making it among the most preferred one. It can be obtained in general from waste heat or temperature gradient. Recent several reports prove that it is possible using nanostructured thermoelectric materials. These aspects shall be discussed in the context of our recent findings.

Audience take-away:

  • In this talk, the audience will learn how much progress has been made in the last about three decades.
  • The audience will learn how this progress in this research has been proliferating due to the use of the theoretical concept of low dimensions or nanostructures, in general.
  • This research may help other faculty to expand their research or teaching and wellbeing of the society against the global warming.
  • This provides a way out for a practical solution to a problem that could simplify or make a designer’s job more efficient.
  • It may improve the accuracy of a design, or provide new information to assist in a design problem of a better futuristic thermoelectric material.


Dr. G. S. Okram did his PhD from Indian Institute of Technology, Bombay (1995), India. He worked at National Institute of Materials Science, Tsukuba, Japan as an STA Fellow (1996-98) and other two research institutes before joining the UGC-DAE Consortium for Scientific Research, Indore in Madhya Pradesh of India as Engineer/ Scientist D in 2001. He is now Engineer/ Scientist G, and has guided four PhD, 6 MPhil, 4 M Tech, 54 MSc and 5 BSc project students, delivered over 86 invited lectures at different national and international (web) conferences, reviewed several reputed journal papers, published over 144 peer-reviewed (reputed) journal papers and 117 conference proceeding presentations with 2001 times citations.
