Quantum oscillation of thermal conductivity and violation of Weidemann-Franz law in TaAs${}_2$ and NbAs${}_2$

X. Rao, X. Zhao, X. -Y. Wang +5

We report a study of thermal conductivity and resistivity at ultra-low temperatures and in high magnetic fields for semi-metal materials TaAs${}_2$ and NbAs${}_2$ by using single cryst…
