Transmission coefficient as a function of the electron energy for the SMN of , where , , and . For even , (a) , (b) , (c) , and (d) , respectively. For odd , (e) , (f) , (g) , and (h) , respectively.
(a) Relation between and in the SMN with , 5, and 8, respectively. is the energy deviation of the nearest peak from . (b) The relation between the quality factor of the perfect transmission peaks in the band gap and in the SMN with . There are three perfect transmission peaks in the band gap of as shown in Fig. 1(b) . These three peaks are located at the electron energies , , and , respectively.
Wave functions of the electron in the nanowire . The electronic states are almost extended when (a) and (b) , respectively. The electronic states are localized when (c) and (d) , respectively.
