Possible Health Hazards Associated with the Use of Toxic Metals in Semiconductor Industries: Swaran J.S. FLORA. Division of Pharmacology and Toxicology, Defence Research and Development Establishment, Gwalior, India— Gallium Arsenide (GaAs), Indium Arsenide (InAs) and Indium Phosphide (InP) are the intermetall ic compounds that are recognised as a potential health risk to workers occupationally...

There is no organometalic compound of Indium known to exist naturally in the human body. However, a number of compounds prepared with ¹¹¹In have been evaluated for localization studies. The useful radioactive decay characteristics and the suitable chemical properties of the metal ion have drawn attention of many investigators resulting in the preparation of numerous ¹¹¹In labeled compound...

Abstract: In this work we investigate the electronic, optical, dynamic and thermoelectric properties of ternary copper-based Chalcogenides CuSbX2 (X= S, Se) compounds. Calculations are based on density functional theory and the semi-classical Boltzmann theory. Computations have been carried out by using Quantum-Espresso (PWSCF) package and ab-initio pseudo-potential technique. To estimate the e...

Abstract Indium chloride bath was characterized towards the application of low-temperature thermal compression bonding. The electrochemical behavior indium analyzed using cyclic voltammetry method. Electrochemical deposition carried out at various factors on different materials such as copper, nickel, and cobalt. Based results obtained from blanket films, bumps were electrochemically fabricated...

Zintl compounds with chemical formula Yb5M2Sb6 (M = Al, Ga, and In) form one of two known A5M2Pn6 structure types characterized by double chains of corner-linked MPn4 tetrahedra bridged by Pn2 dumbbells. High temperature electronic and thermal transport measurements were used to characterize the thermoelectric properties of Yb5M2Sb6 compounds. All samples were found to exhibit similar high p-ty...

Since transition metal impurities affect the electronic and optical properties of semiconductors [1], it is important to understand the role of such unavoidable impurities on those properties. At the same time, transition metals in semiconductors can be used in other unusual situations. The energy levels related to transition metal impurities are aligned with respect to each other for the same ...

The phase diagram of the ternary system L i I n S b is determined at 400 °C by electrochemical techniques. The lithium content of samples with different In : Sb ratios is varied by coulometric titration. The equilibrium lithium activities are obtained from emf measurements. Two new ternary compounds, Li3InSb2 and Li6InSb3 with a wide range of stoichiometry, exist along the quasibinary cut InSb-...

New perylene monoimides, diimides and bis-diimides have been designed and synthetized. A detailed investigation of the synthesis of these compounds has also been performed in order to highlight the crucial factors for obtaining a specific class of molecules. Specifically, the attention has been focused on the synthesis of the intermediate perylene monoimides which are very useful precursors for...
