We report on a class of quantum spin Hall insulators (QSHIs) in strained-layer $\mathrm{InAs}/\mathrm{GaInSb}$ quantum wells, in which the bulk gaps are enhanced up to fivefold as compared to the binary $\mathrm{InAs}/\mathrm{GaSb}$ QSHI. Remarkably, with consequently increasing edge velocity, the edge conductance at zero and applied magnetic fields manifests time …
