Structural studies on Te-rich Ge-Te melts
The structure of liquid Ge15Te85, Ge25Te75 and Ge33Te67 alloys has been studied by neutronand X-ray diffraction. Datasets obtained by the two techniques have been modelled simultaneously with the reverse Monte Carlo simulation method. As a result, the first coordination numbers and nearest neighbour distances for the studied alloys were estimated. On the base of the experimental data, Ge-Ge bon...
متن کاملPulsed laser deposited GeTe-rich GeTe-Sb2Te3 thin films
Pulsed laser deposition technique was used for the fabrication of Ge-Te rich GeTe-Sb2Te3 (Ge6Sb2Te9, Ge8Sb2Te11, Ge10Sb2Te13, and Ge12Sb2Te15) amorphous thin films. To evaluate the influence of GeTe content in the deposited films on physico-chemical properties of the GST materials, scanning electron microscopy with energy-dispersive X-ray analysis, X-ray diffraction and reflectometry, atomic fo...
متن کاملNucleation Studies on Ionic Melts
INTRODUCTION Previous work on crystal nucleation in one-component melts has largely been confined to molecular liquids or metals. Molecular liquids have been studied in bulk", and in the form of clouds of droplets produced by condensation in supersaturated vapourv". Metals have also been studied in bulk 7, 8, and as droplets of microscopic size. These were produced either singly by melting smal...
متن کاملClast-rich H-chondrite Impact Melts
Introduction: The H-chondrite parent asteroid provides the second-most abundant type of meteorites that currently reach Earth's surface [1]. These rocks recorded their parent asteroid's collisional history and melted H-chondrites chronicle the most severe cratering events. Samples and Methods: Seven samples of clast-rich impact melt rocks from the La Paz Icefield, Antarctica were analyzed in Pl...
متن کاملStudies on structural, electrical, and optical properties of Cu doped As–Se–Te chalcogenide glasses
Cu doped chalcogenide ChG glassy films in the As–Se–Te glass system have been prepared using thermal evaporation techniques. Single-source evaporation from bulk 1−x As0.40Se0.35Te0.25+x Cu glasses with x=0.05, 0.075, 0.10, 0.125, and 0.15, as well as dual-source coevaporation from As-chalcogenide and Cu-chalcogenide binary glasses as source materials, has been explored. We have shown that it is...
