| The variation of the energy gap E g with the width L of the TI strip region for different strength R of the SIA term in a symmetry geometry. The black square symbol corresponds to the case of R = 0, the blue triangle symbol to the strength R = 80 meV·nm, and the red circle symbol to the strength R = 160 meV·nm. Here it is assumed that Δ = 1.6 meV and W = 100 nm. |
