Predicted High $n$-Type $zT$ and Ultralow Lattice Thermal Conductivity in A${}_2$AgIrCl${}_6$ (A = Cs, Rb)

Neeraj Kulhari, Krishna Swaroop Sharma, Sung Gu Kang +1

A useful thermoelectric device must impede heat flow without impeding charge transport. Here, we examine how closely cubic Cs${}_2$AgIrCl${}_6$ and Rb${}_2$AgIrCl${}_6$ approach this balan…
