Surface Morphology Dynamics in ITO Thin Films

Surface morphology diagram for cylinder-forming block copolymer thin films.

We investigate the effect of the ordering temperature (T) and film thickness (h(f)) on the surface morphology of flow-coated block copolymer (BCP) films of asymmetric poly(styrene-block-methyl methacrylate). Morphology transitions observed on the ordered film surface by atomic force microscopy (AFM) are associated with a perpendicular to a parallel cylinder BCP microphase orientation transition...

Optoelectronic Properties of ZnSe, ITO, TiO2 and ZnO Thin Films

Zinc selenide (ZnSe) a II-VI compound semiconductor with cubic zinc blende structure and a direct bandgap of 2.7 eV is found to be a very promising material for optoelectronic devices (Venkatachalam et al., 2007a). Semiconductor heterostructures employing zinc selenide and related alloys are an option for the production of optoelectronic devices emitting in the blue – green spectral range (Haas...

Fabrication and Characteristics of RF Magnetron Sputtered ITO Thin Films

Indium tin oxide (ITO) films have been deposited onto glass substrates by ifmagnetron sputtering without insitu substrate heating. The as-deposited films have an electrical resistivity of 5x1O a-cm, visible transmittance of about 85%, and infrared (IR) reflectance of above 80% at 5 jim. The effect of sputtering parameters on the deposition rate and the electrical and optical properties of ITO f...

Structural Properties of Post Annealed ITO Thin Films at Different Temperatures

Indium tin oxide (ITO) thin films were deposited on glass substrates by RF sputtering using an ITO ceramic target (In2O3-SnO2, 90-10 wt. %). After deposition, samples were annealed at different temperatures in vacuum furnace. The post vacuum annealing effects on the structural, optical and electrical properties of ITO films were investigated. Polycrystalline...
