Abstract: A simple room temperature ethanol assisted alcoholysis synthesis was adopted for the preparation of Sn doped indium oxide nanoparticles. Initially, pure indium oxide nanoparticles prepared using the method results in nanocubes, sized about 80 nm was identified using TEM analysis. When the dopant Sn was added at lower concentration the formed cubes were found to contain tiny particles inside nanocubes. As the concentration of Sn increases, it is observed that the particles were no more in cubical shape. For higher concentration of Sn, the formed particles were taken the shape of nanorods which are bunched together. This is one of the interesting results obtained for room temperature chemical synthesis. The concentration of the metal dopant was analyzed using XPS analysis and the obtained XRD pattern showed the dopant shift in 2θ. This work can be further extended to the field of gas sensors. Because, the metal oxide based gas sensors systems depends on the size and shape of the nanoparticles which can improve the sensing behavior of the material.

Abstract: This study describes a new module that uses micro electrochemical machining, and a new design of a convex-shaped tool, in a precision reclamation process to remove defective Indium-tin-oxide (ITO) nanostructures from the optical PET diaphragm surfaces of a digital-paper display. This process takes very little time to remove the ITO layers easily and cleanly and is highly efficient both technically and economically. A small end radius of the cathode or a thin cathode of the bulge-form tool takes less time for the same amount (20 nm) of ITO removal. A large diameter of the cathode of the bulge-form tool combined with a small gap between the cathode and the workpiece corresponds to a higher removal rate of ITO. A high rotational speed of the bulge-form tool can also improve dregs discharge and allows a higher feed rate of the optical PET diaphragm. This higher feed rate combined with enough voltage results in a shorter machining time.

Abstract: The low yield of ITO thin film deposition is an important factor in optoelectronic semiconductor production. A recycle fabrication module uses micro electroremoving as a precision machining process with a new design of inner wedge-form tool to remove the defective Indium-tin-oxide (ITO) nanostructure from the optical PET surfaces of digital paper display is presented in current studies. The adopted precision recycle process requires only a short period of time to remove the ITO nanostructure easily and cleanly is based on technical and economical considerations and is highly efficient. In the current experiment, a higher feed rate of the optical PET diaphragm combines with enough electric power to drive fast micro electroremoving. A large slant angle of the cathode and a small arc rounding radius of the anode takes less time for the same amount of ITO removal. High rotational speed of the electrodes can improve the effect of dregs discharge and is advantageous to associate with the fast feed rate of the workpiece (optical PET diaphragm). A small rotational diameter of the anode accompanied by a small width of the cathode corresponds to a higher removal rate for the ITO nanostructure.
