Optical and electrical properties of nanolaminate dielectric structures

Effect of a Discontinuous Ag Layer on Optical and Electrical Properties of ZnO/Ag/ZnOStructures

“…Our research shows that increasing the sputtering time increases the density and size of the metal granules, which is the reason for the increase in electrical conductivity. These results are reported for TiO 2 /Ag/TiO 2 nanolaminate structures [15]. A similar dependence for the studied samples ZnO/Ag/ZnO is presented in Table 2 for sample 1 (7 s sputtering time) and sample 3 (10 s).…”

“…In previous articles [14][15][16], the relationship between optical transmission and sheet resistance of nanolaminate structures of the ZnO/Ag/ZnO type, depending on the thickness of the Ag layer (or deposition time) has been reported. The effect of the thickness of the top layer (ZnO above Ag nano-granules) is also studied in this research.…”

“…Usually, TCOs have a semiconductor behavior as a negative temperature coefficient of receptivity (TCR). The nanolaminate structure with metal granulate demonstrates metallic conductivity because it has a positive TCR [15]. Therefore, the carriers are delocalized due to thermal activation, and conductivity is dominated by phonon scattering.…”

“…The advantages of this approach are reproducibility, effective process control, and a selective formation of conductive areas in a dielectric structure. Nanolaminate structures with dielectric layers such as TiO 2 , MoO x , and Al 2 O 3 [14], and various metals such as Ag, Cr, Ni, and Pt [15] have been studied. These studies were conducted for various applications of OMO structures [16][17][18] such as indium-free TCO, optoelectronic devices, energy and flexible electronics, and flexible photovoltaic cells.…”
