Alloys as Electricity-generating Allies

Getting to distant planets for space exploration is only half the challenge—packing, transporting and generating energy for these missions requires highly specialized technologies. The 2015 film The Martian, for example, depicts the protagonist using a thermoelectric generator to fend off Mars’ unforgiving cold.

Tuning the phase to achieve peak thermolectric zT at the temperature of interest is a challenge for GeTe thermoelectric application. In this research, IHPC team used first-principles calculation to reveal the important role of atomic doping on structure stability, and we also explored the electronic band structure which is fundamental material property for thermoelectric material design.

The A*STAR-affiliated researchers contributing to this research are from  Institute of Materials Research and Engineering (IMRE) and Institute of High Performance Computing (IHPC).
