Electrical and thermal properties of silver nanowire fabricated on a flexible substrate by two-beam laser direct writing for designing a thermometer.

ABSTRACT: Accurate knowledge of electrical conductivity and thermal conductivity temperature dependence plays a crucial role in the design of a thermometer. Here, by using a two-beam laser direct writing system, an individual silver nanowire (AgNW) with well-defined dimensions is fabricated on a polyethylene terephthalate (PET) substrate. The temperature dependence of the resistivity of the fabricated AgNW is measured ranging from 10 to 300 K, and fitted with the Bloch-Grüneisen formula. The residual resistivity ((1.62 ± 0.20) × 10^-7 Ω m) of the AgNW is larger than that of the bulk material (1 × 10^-11 Ω m). The electron-phonon coupling constant of the AgNW is (1.08 ± 0.13) × 10^-7 Ω m, which is larger than that of the bulk silver (5.24 × 10^-8 Ω m). Moreover
