Researchers from Germany, Italy, and the UK have achieved a major advance in the development of materials suitable for on-chip energy harvesting. By composing an alloy made of silicon, germanium and tin, they were able to create a thermoelectric material, promising to transform the waste heat of computer processors back into electricity.

With all elements coming from the 4th main group of the periodic table, these new semiconductor alloy can be easily integrated into the CMOS process of chip production...

Researchers have created a new and potentially paradigm-shifting high-performance thermoelectric compound. The team created a new hybrid compound in which the crystalline and amorphous sublattices are intertwined into a one-of-a-kind crystal-amorphic duality.

Thermoelectrics directly convert heat into electricity and power a wide array of items – from NASA’s Perseverance rover currently exploring Mars to travel coolers that chill beverages.

A Clemson University physicist has joined forces with collaborators from China and Denmark to create a new and potentially paradigm-shifting high-performance thermoelectric compound.

A material’s atomic structure, which is how atoms arrange themselves in space and time, determines its properties...

Material created with high heat yields record power output density. With energy conservation expected to play a growing role in managing global demand, materials and methods that make better use of existing sources of energy have become increasingly important. Researchers reported this week they have demonstrated a step forward in converting waste heat – from industrial smokestacks, power generating plants or even automobile tailpipes – into electricity.

The work, using a thermoelectric compound composed of niobium, titanium, iron and antimony, succeeded in raising the material’s power output density dramatically by using a very hot pressing temperature – up to 1373 Kelvin ...
