Opis:: The influence of the modes of laser treatment on the structural-phase state and electrical properties of thin films and epitaxial layers In4Se3, In4Te3, as well as on the thin-film structures with Schottky barrier of type Au - In4Te3 (In4Se3) are investigated. Thin films In4Se3, In4Te3 received by pulsed laser deposition of stoichiometric homogeneous crystalline materials on a dielectric substrate. The epitaxial layers of In4Se3, In4Te3 were obtained by liquid phase epitaxy. Metal contacts are created by thermal spraying of the respective metals in a vacuum p 10-6 ÷ 10-7 Torr. For the correction of electrophysical characteristics of the studied structures the pulse laser irradiation (PLI) with 1,06 m, 1 ÷ 4 ms was used. The surface morphology of the films on various stages of formation of the structures was investigated by SEM and electron diffraction, and the phase composition was monitored by method X - ray spectral electron probe microanalysis. Study of IV characteristics of film contacts Me - In4Te3 (In4Se3) allowed further identify the phase transformation and the basic mechanisms of charge transport in barrier structures after PLI. Investigation of the spectral photosensitivity of film structures showed that under optimum conditions the laser correction can be obtained the shift of the spectral characteristics from 1,7÷1,8 microns to longer wavelengths. The investigated barrier structures may be promising for use as a photodetector for fiber optic communication lines.

Opis:: Cassiterite and base-metal mineralisation from the Gierczyn mine on the Karkonosze-Izera Massif, Poland has been studied using electron microprobe and LA-ICP-MS (Laser Ablation Inductively Coupled Plasma Mass Spectrometry) techniques in order to determine the content of indium in the ore minerals. The main carriers of this element are sphalerite (up to 433 μ/g of In), chalcopyrite (up to 117 μ/g of In) and cassiterite (up to 0.02 wt.% In). Trace element contents of sulphides, especially Ga in chalcopyrite intergrown with sphalerite in comparison with chalcopyrite without sphalerite, may indicate metamorphic re-equlibration and suggests that the ore minerals might recrystallized and underwent metamorphism in conditions of greenschist/amphibolite facies. Although the deposits in the Stara Kamienica Schist Belt are not of economic value, they can contribute to better understanding of the relations between trace element partitioning and the formation of ore minerals.

Opis:: InSb nanowire (NW) arrays were prepared by pulsed electrodeposition combined with a porous template technique. The resulting polycrystalline material has a stoichiometric composition (In: Sb = 1:1) and a high length-to-diameter ratio. Based on a combination of Fourier transform infrared spectroscopy (FTIR) analysis and fi eld-effect measurements, the band gap, the charge carrier polarity, the carrier concentration, the mobility and the effective mass for the InSb NWs was investigated. In this preliminary work, a transition from p -type to n -type charge transport was observed when the InSb NWs were subjected to annealing.

Opis:: The demand for indium is increasing every year. This metal is mainly used as indium tin oxide (ITO) in the production of transparent conductive coatings for liquid crystal displays (LCD). This paper focuses on biohydrometallurgical methods used for the recovery of indium and tin from LCD sourced from spent mobile phones. Bioleaching experiments were carried out in two different leaching media: 9K medium and H2SO4 solution, using mixed, adapted bacteria Acidothiobacillus ferrooxidans and Acidothiobacillus thiooxidans. The main aim of this study was to evaluate the potential and efficiency of indium and tin extraction in the presence of acidophilic microorganisms. Within 35 days, using 9K medium, 55.6% of indium was bioleached, whereas the chemical leaching resulted in a value of 3.4%. Leaching efficiency of tin was 90.2% on the 14th day of the experiment for the biological system (9K) and 93.4% on 21st day of control leaching.

Opis:: The influence of pure and mixed culture of A. ferrooxidans and A. tiooxidans as well as different pulp density (1 and 2%) of LCD panels on the In and Sn bioleaching efficiency was investigated. Pulp density is one of the factors affecting the metals extraction efficiency during biological leaching. It has been shown that lower pulp density results in higher indium and tin dissolution. The A. ferrooxidans bioleaching system showed better metal extraction results than A. thiooxidans, especially for tin, indicating the special role of iron and A. ferrooxidans in tin recovery. The highest leaching rate of both indium (94.7%) and tin (98.2%) was obtained using iron and sulfur medium inoculated with mixed bacteria and a pulp density of 1% w/v.

Opis:: Experiments were performed in an interdigital micromixer with 30 microchannels (40 μm width of each channel) to separate In³⁺, Fe³⁺ and Zn²⁺ from sulfate solutions using Di-(2-ethylhexyl)phosphoric acid (D2EHPA) as the extractant. The effects of pH, extractant concentration and flow rate on the extraction efficiency and flow rate on mass transfer coefficient of In³⁺, Fe³⁺ and Zn²⁺ were investigated. At a phase flow rate of 7.0 mL/min and initial solution pH of 0.423, the extraction efficiency of In³⁺, Fe³⁺ and Zn²⁺ was 99.29%, 3.43% and 2.54%, respectively and mass transfer coefficient of In³⁺, Fe³⁺ and Zn²⁺ was 144.307 s^-1,1.018 s^-1 and 0.750 s^-1. Then, the loaded organic phase was stripped in an interdigital micromixer. At a phase flow rate of 9.0 mL/min and HCl concentration of 160 g/L, stripping efficiency of In³⁺ was 98.92% and mass transfer coefficient of In3+ was 169.808 s^-1, while concentration of Fe³⁺ and Zn²⁺ was lower than 0.005 g/L with good separation of In³⁺ from Fe³⁺ and Zn²⁺.

Opis:: In this study, molten salt electrorefining was used to recover indium metal from In-Sn crude metal sourced from indium tin oxide (ITO) scrap. The electrolyte used was a mixture of eutectic LiF-KF salt and InF₃ initiator, melted and operated at 700°C. Voltammetric analysis was performed to optimize InF₃ content in the electrolyte, and cyclic voltammetry (CV) was used to de-termine the redox potentials of In metal and the electrolyte. The optimum initiator concentration was 7 wt% of InF₃ , at which the diffusion coefficients were saturated. The reduction potential was controlled by applying constant current densities of 5, 10, and 15 mA/cm² using chronopotentiometry (CP) techniques. In metal from the In-Sn crude melt was deposited on the cathode surface and was collected in an alumina crucible.

Opis:: The simultaneous determination of Ga(III) and In(III) in environmental water samples was described. The procedure was based on adsorptive stripping voltammetry using an in situ plated bismuth film electrode as a working electrode. In order to obtain low detection limits and satisfactory separations of gallium and indium peaks on the voltammogram, cupferron was used as a complexing agent. The optimum composition of the supporting electrolyte was found to be: 0.1 mol l-1 acetate buffer (pH=5.0), 2 × 10-4 mol l-1 cupferron, 2 × 10-4 mol l-1 Bi(III), optimal voltammetric parameters were found to be: accumulation potential -0.9 V, accumulation time 60 s. The linear range of Ga(III) as well as In(III) was observed over a concentration range from 2.5 × 10-8 mol l-1 to 1.5 × 10-6 mol l-1. The method was satisfactorily applied to the simultaneous quantification of gallium and indium in environmental water samples. This facilitated a promising application of the recommended procedure for monitoring the environment, which is necessary to evaluate the soil-plant system.

Opis:: This paper investigates the influence of film thickness on the electrical and mechanical properties of transparent indium tin oxide (ITO) thin films. Two groups of ITO thin films deposited on unheated substrates were prepared by the radio-frequency magnetron sputtering technique. The biaxial residual stress and surface roughness for two groups of ITO thin films were measured by a Twyman–Green interferometer and a Linnik microscopic interferometer, respectively. The electrical resistivity of the ITO films was measured by a four-point probe apparatus, the thickness was determined mechanically with a profilometer. The measurement results show that the average resistivity of ITO thin films decreases with increasing the deposited thickness. The compressive residual stress in the ITO thin films decreases with increasing the deposited thickness. We also find that an anisotropic stress in the two groups of ITO films is more compressive in a certain direction. The RMS surface roughness in the two groups of ITO films is less than 1 nm.
