Researchers at Marie Curie-Skłodowska University, in Lublin, Poland have demonstrated the importance of thermoelectric effects in nanostructures. For about 200 years physicists have sought the efficient turning of heat into electricity in the field called thermoelectrics. Scientists have long known that in conducting materials the flow of energy in the form of heat is also […]

Progress on the Thermoelectric Front
February 21, 2011 | 1 Comment
Researchers from Boston College, MIT, Clemson University and the University of Virginia have used a nanotechnology processing technology to achieve a 60 to 90 percent increase in the thermoelectric figure of merit of p-type half-Heusler, a common bulk semiconductor compound. The team’s paper has been published in the journal Nano Letters. Half-Heusler compounds and the […]

Simple & Common Materials For Record Breaking Thermoelectric
January 26, 2011 | 1 Comment
Northwestern University researchers have placed nanocrystals of rock salt into lead telluride, creating a thermoelectric material that can harness electricity from heat sources. The material exhibits a high thermoelectric figure of merit that is expected to enable 14 percent of heat waste converted to electricity, a new scientific record. Chemists, physicists and material scientists at […]
