Reentrant Quantum Spin Hall States in Charge Density Wave Phase of Doped Single-Layer Transition Metal Dichalcogenides

Jun-Ho Lee, Young-Woo Son

Using first-principles calculation methods, we reveal a series of phase transitions as a function of electron doping in single-layer 1T${}^{\prime }$-MoTe${}_2$ and 1T${}^{\prime }$-WTe${}_2$ exhibiting qua…
