We consider the cylindrical nanowire geometry shown in Fig. 17.1, with an incident plane wave normal to the cylinder axis and with an amplitude Eg. This is the simplest case to solve analytically and the one most often treated in experimental spectroscopic investigations of single nanowires. Possible orientations of linearly polarized incident light with respect to the wire axis are bounded by two cases. The first is the transverse magnetic (TM) polarization where the electric field is polarized parallel to the wire axis, and the second is the transverse electric (TE) polarization where the electric field is polarized perpendicularly to the wire axis. In TM polarization, the condition of continuity of the tangential electric field is expected to maximize the internal field, while in TE polarization, the dielectric mismatch should suppress the internal field. The incident plane wave may be expanded in cylindrical functions as ...

Figure 6.37 Dependence of (a) electrical conductivity, Seebeck coefficient, and (b) power factor on the weight fraction of Tellurium nanowires in PEDOT PSS/Te composite film [17].

It was shown that the Seebeck coefficient of the PEDOT PSS/Te hybrid is significantly larger than that of the pure PEDOT PSS polymer. Besides, electrical conductivity of the hybrid films is also higher than those of both the Te nanorods and PEDOT PSS polymer, indicating that the PEDOT PSS protects the Te from oxidation and improves inter particle contact. By varying the Te content, it was found the electrical conductivity and the TE power factor of the composite exhibit a peak at an intermediate nanowire mass fraction, whereas the Seebeck coefficient increases monotonically with increasing Te, as shown in Figure 6.37 [17].

Fig. 25.1 a Size and temperature dependence of the Debye-Waller factor r (amplitude of lattice vitaation) of the nearest neighbor within chains for Te systems. Solid lines are the respective correlated Einstein model fit to t-Te in the 0.5-nm-thick films (solid circles). The triangles denote for bulk t-Te the squares denote fra- the 300-nm-thick films (reprinted with permission from [15]), and b the temperature dependences of the interplanar spacing d of the (220) plane for the annealed Ni nanowire arrays (curve a) and the annealed bulk Ni (curve b) show the same trend of size and temperature dependence (rejainted with permission from [16])...
