(color online) Spatial resolved LDOS and transmission spectra of the vertically stacked β/δ p–i–n junction at current peak (V_bias = 0.125–0.50 V) (a)–(d) and valley (V_bias = 1.125–1.25 V) (e)–(h), respectively. The lengths of the intrinsic regions are L₁in panels (a) and (e), L₂ in panels (b) and (f), and L₃ in panels (c) and (g), respectively. The Fermi levels of the left and right electrodes are denoted by E_f,L and E_f,R, respectively.
