Ion implantation and low-temperature epitaxial regrowth of GaAs [PDF]

, 1981
Channeling and transmission electron microscopy have been used to investigate the parameters that govern the extent of damage in ion‐implanted GaAs and the crystal quality following capless furnace annealing at low temperature (∼400 °C). The implantation‐

Effect of the degree of plastic deformation on the thermal electromotive force of cu-x5crni1810 steel thermocouple [PDF]

Science of Sintering, 2018
The thermal electromotive force (TEMF) and the thermal electromotive force coefficient (TEMFC) of the thermocouple consisting of a copper wire and an (X5CrNi1810) steel wire plastically deformed under tension or bending conditions were found to ...

Influence of grinding and pressing of the powder 50.0 wt% Fe, 47.0 wt% BaTiO3 and 3.0 wt% TiO2 on morphology, microstructure and magnetic properties [PDF]

Science of Sintering
Mixing the powders Fe (50.0 wt%), BaTiO3 (47.0 wt%) and TiO2 (3.0wt%) provides a mixture consisting of a matrix of smaller particles BaTiO3 in which larger particles Fe and TiO2 were embedded.

Processes at lithium-hydride/deuteride surfaces upon low energy impact of H/D

Frontiers in Physics, 2023
Sputtering, reflection, and retention processes at amorphous and crystalline lithium hydride surfaces due to impact of low energy (1–100 eV) hydrogen and deuterium atoms over the range of 0o −85o angle of incidence at 300 K surface temperature were ...

Photocatalytic Crystalline and Amorphous TiO₂ Nanotubes Prepared by Electrospinning and Atomic Layer Deposition

Molecules, 2021
In this work core/shell composite polymer/TiO2 nanofibers and from those TiO2 nanotubes were prepared. First, poly(vinyl alcohol) (PVA) and poly(vinylpyrrolidone) (PVP) fibers were synthetized by electrospinning.

Kinetically Controlled Two-Step Amorphization and Amorphous-Amorphous Transition in Ice

Physical Review Letters, 2017
We report the results of in situ structural characterization of the amorphization of crystalline ice Ih under compression and the relaxation of high-density amorphous (HDA) ice under decompression at temperatures between 96 and 160 K by synchrotron x-ray diffraction.

Machine learning for glass science and engineering: A review

Journal of Non-Crystalline Solids: X, 2019
The design of new glasses is often plagued by poorly efficient Edisonian “trial-and-error” discovery approaches. As an alternative route, the Materials Genome Initiative has largely popularized new approaches relying on artificial intelligence and ...

Theory of amorphous ices

, 2014
We derive a phase diagram for amorphous solids and liquid supercooled water and explain why the amorphous solids of water exist in several different forms.

Amorphous interface layer in thin graphite films grown on the carbon face of SiC [PDF]

, 2011
Cross-sectional transmission electron microscopy (TEM) is used to characterize an amorphous layer observed at the interface in graphite and graphene films grown via thermal decomposition of C-face 4H-SiC.
