This study was conducted to evaluate the potency of the newly prepared germanium L-cysteine-alpha-tocopherol complex [germanium dichloro tetrakis (L-cysteinyl-alpha-tocopherol amide) dichloride] as a protective agent against gamma-irradiation-induced free radicals production and liver toxicity. Male Swiss albino rats were injected intraperitoneally with the germanium complex in a concentration ...

for an Invited Paper for the MAR08 Meeting of The American Physical Society Dangling-bond defects and hydrogen passivation in germanium JUSTIN R. WEBER, Department of Physics, University of California, Santa Barbara, California 93106-9530, USA The application of germanium in complementary metal-oxide semiconductor (CMOS) technology is hampered by high interface-state densities, the microscopic ...

germanium nanowires (genws) were synthesized using chemical vapor deposition (cvd) based on vapor–liquid–solid (vls) mechanism with au nanoparticles as catalyst and germanium tetrachloride (gecl4) as a precursor of germanium. au catalysts were deposited on silicon wafer as a thin film, firstly by sputtering technique and secondly by submerging the silicon substrates in au colloidal solution, wh...

We report the application of the technique of infrared transmission to measure the temperature of silicon wafers during the growth of silicon-germanium alloy heteroepitaxial layers in a rapid thermal processing system. The silicon-germanium alloy layers have negligible absorption at 1.3 and 1.55 pm over wide ranges of thickness, composition, and strain condition. The substantial improvement of ...

Germanium dioxide has many applications in the optoelectronics sector and is the subject of substantial research interest. In this contribution we report the preparation of germanium dioxide nanoparticles (NPs) of varied sizes and morphologies using a facile sol-gel methodology that requires no addition of templating agents (e.g., surfactants). Morphological control is achieved by tailoring the...

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...

A new germanium(II) phosphate, sodium tetra-germanium tris-(phosphate), Na[Ge(4)(PO(4))(3)], has been synthesized by a solid-state reaction. The compound is isotypic with A[Sn(4)(PO(4))(3)] (A = Na, K, NH(4)). It features a [Ge(4)(PO(4))(3)](-) framework made up of GeO(3) pyramids and PO(4) tetra-hedra, which are linked by shared corners, yielding a three-dimensional structure. The crystal stud...

A Monte Carlo simulation code has been developed that calculates the isotopes produced by spallation and propagates the products of radioactive decays for the purpose of studying activation backgrounds in space based gamma-ray telescopes. This code has been applied to study a Compton telescope consisting of two large arrays of position sensitive germanium detectors. Activation of the germanium ...

We observe a sharp feature in the ultra-low-temperature magnetoconductivity of degenerately doped Ge:Sb at H-25 kOe, which is robust up to at least three times the critical density for the insulator-metal transition. This field corresponds to a low-energy scale characteristic of the special nature of antimony donors in germanium. Its presence and sensitivity to uniaxial stress confirm the notio...

We present experimental evidence showing that the period of the rippled surface structure induced on germanium by 1.06-microm laser pulses undergoes a discontinuous shift above a certain threshold intensity. The measured shift, as a angle of incidence of the damaging beam, is quantitatively interpreted as a transition between a regime of inhomogeneous melting controlled by radiation-remnant fie...
