Synthesis of Germanium Dioxide Microclusters on Silicon Substrate in Non-Aqueous Solution by Electrochemical Deposition

We report the formation of crystalline germanium dioxide (GeO2) microclusters on n-Si (100) electrodeposited in non-aqueous electrolyte (a mixture of 5 vol.% germanium tetrachloride (GeCl4) and dipropylene glycol (C6H14O3) ) at current density of 20 mA/cm 2 for 200 sec. Pt, C and Ge are used as an anode while Si acts as a cathode. Fieldemission scanning electron microscopy (FESEM) images show t...

The Erythropoietic Action of Germanium Dioxide

Injections were made of a sterile 0.4 per cent solution of germanium dioxide into four lots of mature male and female albino rats. Exact conditions of control were maintained. To two lots there was administered in four doses at intervals of 4 days a total of 6.6 mg. of the oxide per kilo of body weight. To two lots there was given in three doses at like intervals a total of 45 mg. of the compou...

Silicon/silicon Dioxide Nanostructure in Electrostatic Field

Paper presents a numerical analysis of quantum states and probability ψψ* function of a Si/SiO2 nanostructure in varying electrostatic field. The position of probability function peak xp is traced and the bias, under which it abandons the structure (emission or discharging bias), is determined. Variations of the ground state energy with the bias is also examined. The Poisson Schrödinger model o...

Modeling Process-Dependent Thermal Silicon Dioxide (SiO2) Films on Silicon

This study attempts to model correctly the process dependence of thermal SiO2 film physical structures and their associated densities, as well as high frequency dielectric constants, so as to provide a foundation for a ULSI process-dependent device reliability simulator. By exploring the characteristic signature of ellipsometric data reduced using a one-layer film model, and comparing it to a t...
