Erratum: Spin Chirality Tuning and Topological Semimetals in Strained ${\mathrm{HgTe}}_x{\mathrm{S}}_{1-x}$ [Phys. Rev. Lett. 114, 236805 (2015)]

Figure 1

Topological phase diagram of strained ${\mathrm{HgTe}}_x{\mathrm{S}}_{1-x}$ alloys ($x$ alloy concentration, $\beta$ strain). The phases are indicated by colors: strong topological insulator (STI) with mirror Chern number $c_{\mathrm{m}}=-1$ (red), STI with $c_{\mathrm{m}}=+1$ (green), Weyl semimetal (WSM I & WSM II, grey), and normal semimetal (blue).

Figure 2

Weyl semimetal phase WSM II in tensile strained HgTe ($\beta =0.97$). (a) Ab initio KKR band structure along the $-Z-\mathrm{\Gamma }-Z$ line showing a band gap between the topmost valence and lowest conductance bands. (b) Width $E_{\mathrm{g}}$ of the band gap in the $k_x{k}_y$ plane with $k_z=+56\mathrm{m}{\AA }^{-1}$, indicated as color scale (black: $E_g>7\mathrm{meV}$, white: $E_g=0\mathrm{meV}$; TB calculation). Four Weyl points are marked by green dots.
