silver nanowires were synthesized by solvothermal method through reducing silver nitrate (agno3) with ethylene glycol (eg) in the presence of polyvinylpyrrolidone (pvp). in order to prevent the agglomeration of ag+ in the initial ag seeds formation, sodium chloride (nacl) was added into the solution to form agcl colloids. by dissolving agcl in the late stages, ag+ ions were released into the so...

Nano structures such as nanowires, nanobeams and nanoplates have been investigated widely for their innovative properties. In this paper the buckling of nanowires surrounded in a Winkler - Pasternak elastic medium has been examined based on the nonlocal Euler-Bernoully model with considering the surface effects. In the following a parametric study that explores the influence of numerous physica...

High quality dielectric-semiconductor interfaces are critical for reliable high-performance transistors. This paper reports the in situ metal–organic chemical vapor deposition of Al2O3 on β-Ga2O3 as a potentially better alternative to most commonly used atomic layer (ALD). The growth is performed same reactor Ga2O3 using trimethylaluminum and O2 precursors without breaking vacuum at temperature...

The templated zeolite-analogue GaPO-34 (CHA structure type) crystallises from a gel precursor Ga2O3 : 2H3PO4 : 1HF : 1.7SDA : 70H2O (where SDA = structure directing agent), treated hydrothermally for 24 hours at 170 °C using either pyridine or 1-methylimizadole as SDA and one of either poorly crystalline ε-Ga2O3 or γ-Ga2O3 as gallium precursor. If the same gels are stirred for periods shorter t...

OBJECTIVE The purpose of this study was to use x-ray diffraction (XRD) to obtain new information about the oxide layers on four representative oxidized high-palladium alloys. METHODS Cast specimens of two Pd-Cu-Ga alloys and two Pd-Ga alloys, with both polished and etched surfaces and air-abraded surfaces, were subjected to oxidation procedures recommended by the manufacturers. The specimens ...

The density of Ga203 liquid in equilibrium with air has been measured at 1800” to 1900°C using an Ir double-bob Archimedean method. The data yield the following description of the density of Gaz03 liquid: p = 4.8374(84)0.00065(12)(T -18S0°C). This density-temperature relationship is compared with the partial molar volume of GazO3 in glasses in the systems CaO-Ga203 -SiOz and Naz0-Ga2O3-SiO2, co...

Junctions with the structure Ag/S(CH2)nT// Ga2O3/EGaIn (where S(CH2)nT is a self-assembled monolayer, SAM, of n-alkanethiolate bearing a terminal functional group T) make it possible to examine the response of rates of charge transport by tunneling to changes in the strength of the interaction between T and Ga2O3. Introducing a series of Lewis acidic/basic functional groups (T = −OH, −SH, −CO2H...

Junctions with the structure Ag(TS)/S(CH2)nT//Ga2O3/EGaIn (where S(CH2)nT is a self-assembled monolayer, SAM, of n-alkanethiolate bearing a terminal functional group T) make it possible to examine the response of rates of charge transport by tunneling to changes in the strength of the interaction between T and Ga2O3. Introducing a series of Lewis acidic/basic functional groups (T = -OH, -SH, -C...

This paper introduces a growth method—suboxide molecular-beam epitaxy (S-MBE)—which enables drastic enhancement in the rates of Ga2O3 and related materials to over 1 ?m h?1 an adsorption-controlled regime, combined with excellent crystallinity. Using Ga + mixture oxygen mole fraction x(O) = 0.4 as MBE source, we overcome kinetic limits that had previously hampered by MBE. We present up 1.6 1.5 ...

Continuous hydrothermal synthesis of metal oxide nanoand microparticles in supercritical water was performed in a continuous flow reactor. The results of investigation of LiCoO2, LiNiO2, LiZnO2, LiCuO2, Ga2O3, CeO2 nanoparticles by HRTEM and XRD analysis were presented.
