Abstract
A two-beam laser fabrication technique is introduced to fabricate the single silver nanowire (AgNW) on polyethylene terephthalate (PET) substrate. The resistivity of the AgNW is (1.31â¯Â±â¯0.05)â¯Ãâ¯10â7â¯Î©Â·m, which is about 8 times of the bulk silver resistivity (1.65â¯Ãâ¯10â8â¯Î©Â·m). The AgNW electrical resistance is measured in temperature range of 10-300â¯K and fitted with the Bloch-Grüneisen formula. The fitting results show that the residue resistance is 153â¯Î©, the Debye temperature is 210â¯K and the electron-phonon coupling constant is (5.72â¯Â±â¯0.24)â¯Ãâ¯10â8â¯Î©Â·m. Due to the surface scattering, the Debye temperature and the electron-phonon coupling constant are lower than those of bulk silver, and the residue resistance is bigger than that of bulk silver. Thermal conductivity of the single AgNW is calculated in the corresponding temperature range, which is the biggest at the temperature approaching the Debye temperature. The AgNW on PET substrate is the low temperature resistance material and is able to be operated stably at such a low temperature of 10â¯K.
