Effect of band inversion on the phonon spectra of Hg _{1– x} Zn _x Te and Hg _{1– x} Cd _x Te semiconductor alloys

Global band convergence design for high-performance thermoelectric power generation in Zintls

“…Nevertheless, Δ changes with compositions, and by alloying two proper parent compounds together and adjusting their ratios, the splitting energy can eventually reach zero (aligned) in a particular composition ( 24 ). In fact, this concept is analogous to that for inducing electronic band inversion in topological materials such as Pb 1− x Sn x Se and Hg 1− x Zn x Te ( 25 , 26 ) and functions universally as a method for tuning the electronic bands of alloys.…”
