Effect of annealing on electrical resistivity of rf-magnetron sputtered nanostructured SnO2 thin films

Optoelectronic studies of sol–gel derived nanostructured CdO–ZnO composite films

“…The roughness of the sample not only describes the light scattering but also gives an idea about the quality of the surface under investigation. Khan et al [23] have reported a kind of inverse trend of resistivity with roughness of nanostructered SnO 2 thin films. In fact, we have observed a similar behavior in the present sol-gel derived CdO-ZnO thin films.…”

Influences of defects and Sb valence states on the temperature dependent conductivity of Sb doped SnO 2 thin films

“…It is known that the electrical contact between the crystalline domains is not perfect in many oxide films [8], carrier scattering at grain boundaries further reduces the conductivity of these materials. Numerous studies [9][10][11] of SnO 2 thin films have been done to improve their electrical conductivity for utilizing them as transparent electrodes. However, underlying influences of defects and dopants on the carrier transportation in SnO 2 based thin films are not yet well understood.…”

A sintering-free, nanocrystalline tin oxide electron selective layer for organometal perovskite solar cells

“…3b and Fig. S3 show that the grains are uniformly distributed within the scanning area, and the film is smooth with a root mean square (RMS) surface roughness of~14.9 nm in an area of 2 μm × 2 μm, smaller than 25.76 nm reported in high-temperature processed films with large particle size [35]. This surface char- acteristic is important for SnO2's applications as ESL.…”
