Conductance of a two-dimensional conductor as a function of l_f/L_x calculated by using the expression Eq. (24) for κ (solid line), compared with that calculated by setting κ = 1 (triangles). Dot-dashed line represents the Boltzmann–Drude (BD) formula G = (n_ee²τ₀/m_e) L_y/L_x, and the dashed line stands for the Landauer–Büttiker (LB) formula G = N_che²/h.
