ITO conducting coatings properties improvement via nanotechnology approach

Abstract

Abstract In this paper the investigation devoted to study and development of the optimized ITO conducting layers are presented and discussed under the conditions of the materials surfaces laser structuration in order to apply the modified conducting materials in the optoelectronics, virus protection, solar energy, microscopy, biomedicine, etc. area. Based on our knowledge and expertise it is established the dramatic change of the main characteristics of the ITO matrix, which surface is modified by the carbon nanotubes (CNTs), and additionally treated by surface electromagnetic waves (SEW) as well. The transmittance and reflection spectral change, increase of the micro hardness and laser strength as well as the increase of the wetting angle and refraction change are discussed due to the covalent bonding between the carbon nanotubes and the near-surface atoms of the matrix materials. As the unique point of the study the effective decrease of the resistivity is established and presented. Quantum chemical simulations are supported the data presented.
