Journal ArticleDOI
Surface characterization and microstructure of ITO thin films at different annealing temperatures
TL;DR: In this paper, the electron beam evaporation method is used to generate an indium tin oxide (ITO) thin film on a glass substrate at room temperature and the surface characteristics of this ITO thin film are then investigated by means of an AFM (atomic force microscopy) method.
Journal ArticleDOI
The effect of annealing on structural, electrical and optical properties of nanostructured ITO films prepared by e-beam evaporation
TL;DR: In this paper, the authors showed that increasing annealing temperature increased the crystallinity of thin films and at 550°C high quality crystalline thin films with grain size of about 37nm were obtained.
Journal ArticleDOI
The effect of deposition rate on electrical, optical and structural properties of tin-doped indium oxide (ITO) films on glass at low substrate temperature
TL;DR: In this paper, the lattice constant and the grain size of tin-doped indium oxide (ITO) thin films with composition of 9.42% SnO 2 and 89.75% In 2 O 3, and impurities balanced have been prepared by electron beam evaporation on glass substrates with different deposition rates at fixed low substrate temperature condition.
Journal ArticleDOI
Influence of heat treatment on structural, electrical, impedance and optical properties of nanocrystalline ITO films grown on glass at room temperature prepared by electron beam evaporation
TL;DR: In this article, annealing temperature of indium tin oxide (ITO) thin films with composition of 9.42% SnO 2 and 89.75% In 2 O 3, and impurities balanced on glass substrates at room temperature were prepared by electron beam evaporation technique and then were annealed in air atmosphere at different temperatures from 350 to 550°C for 1.h.
Journal ArticleDOI

TL;DR: In this article, the effect of the laser fluence and ablation time on the ablation efficiency was studied, and the results showed that the ablated colloid solution by subsequent treatment with 1064 and 532 nm laser pulses yield redistribution of nanoparticles to a smaller mean size.
