| The variation of the energy gap E g with the width L of TI strip region for different width W of NI region in a symmetry geometry. The black line corresponds to the case of W = 0, the blue line to the width W = 10 nm, the purple line to the width W = 20 nm, and the red line to the width W = 100 nm. Here it is assumed that Δ = R = 0. |
