Solid state synthesis from KH and thermoelectric properties of K₈E₈Ge₃₈ (E = Al, Ga, In)
The Kauzlarich lab (Perez and coworkers, Inorganic Chemistry) has recently reported the synthesis, low-temperature thermoelectric properties, structures, and composition of the type-I Clathrates K₈E₈Ge₃₈ (E = Al, Ga, In) using KH, E, and Ge. K₈E₈Ge₃₈ shows significant thermoelectric (zT) improvement over the Si analog (K₈AI₈Si₃₈) due to a reduced electrical resistivity. This work points towards more sustainable cost-effective materials for optimal thermoelectric performance.
