Solution-Based Synthesis of GeTe Octahedra at Low Temperature

Solution-based synthesis of GeTe octahedra at low temperature.

GeTe octahedra were prepared by reaction of equimolar amounts of GeCl2·dioxane and Te(SiEt3)2 in oleylamine, whereas a slight excess of the Te precursor yielded GeTe octahedra decorated with elemental Te nanowires, which can be removed by washing with TOP. The mechanism of the GeTe formation is strongly influenced by the solvent. The expected elimination of Et3SiCl (dehalosilylation) only occur...

CaCu3Ti4O12: Low-Temperature Synthesis by Pyrolysis of an Organic Solution

Temperature-Dependent Electrical Conductivity of GeTe-Based RF Switches

The DC and RF electrical behavior of GeTebased RF switches was characterized in both ON and OFF states at temperatures ranging from 25 K to 375 K. ONstate current-voltage characteristics vary only weakly with temperature, exhibiting Ohmic behavior at all temperatures across the full voltage range measured. OFF-state current varies linearly with voltage at all measured fields for low temperature...

LOW TEMPERATURE SYNTHESIS OF NANOCRYSTALLINE MgAl2O4 SPINEL VIA SUCROSE PROCESS

Abstract: Nanocrystalline MgAl2O4 spinel powder was synthesized using metal nitrates and a polymer matrix-based composed of sucrose and polyvinyl alcohol (PVA). The precursor and the calcined powders were characterized by simultaneous thermal analysis (STA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). According to XRD res...
