Extended Data Fig. 4: Temperature dependence of charge neutrality point (CNP) conductance and thermal activation fitting (device D2).

From: Dual quantum spin Hall insulator by density-tuned correlations in TaIrTe4

Extended Data Fig. 4

The four-probe conductance (Gxx) versus carrier density (n) is shown with temperatures ranging from 250 K to 4 K, along with corresponding thermal activation gap fits. Channel lengths: a,b, Lch = 220 nm; c,d, Lch = 270 nm; e,f, Lch = 550 nm; g,h, Lch = 850 nm; i,j, Lch = 950 nm; k,l, Lch = 1100 nm.
