In this thesis, silver nanowire (Ag NW) networks are embedded into aluminum doped zinc oxide (AZO) to prepare transparent and conducting (TC) films. The nanowires are of different length and diameters according to various reaction times and temperatures. The electrical properties, such as carrier concentration, carrier mobility and resistivity are studied using Van Der Pauw Hall measurement. The optical properties such as Mie scattering, Transmission and Haze are studied from both experimental and simulating results. The best Ag NW embedded TC film shows a low resistivity ~3.6 ×10-4Ω·cm with transmission ~ 85%. The theory of percolation is used to explain the connectivity effect of nanowires on the conductivity and transparency of TC films. Moreover, the optical improvement by adding silver nanoparticles is also discussed and showed. Small nanoparticles with diameter ~20nm can reduce the haze causing by silver nanowire networks.
