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 ...

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.

Simultaneous planar growth of amorphous and crystalline Ni silicides [PDF]
, 1988 We report a solid-state interdiffusion reaction induced by rapid thermal annealing and vacuum furnace annealing in evaporated Ni/Si bilayers. Upon heat treatment of a Ni film overlaid on a film of amorphous Si evaporated from a graphite crucible ...

Precision Synthesis of Silicon Nanowires with Crystalline Core and Amorphous Shell [PDF]
, 2013 A synthetic route to crystalline silicon (Si) nanowires with an amorphous Si shell is reported. Trisilane (Si3H8) and Sn(HMDS)(2) are decomposed in supercritical toluene at 450 degrees C.

Topological Amorphous Metals [PDF]
Physical Review Letters, 2019 We study amorphous systems with completely random sites and find that, through constructing and exploring a concrete model Hamiltonian, such a system can host an exotic phase of topological amorphous metal in three dimensions. In contrast to the traditional Weyl semimetals, topological amorphous metals break translational symmetry, and thus cannot be ...

Influence of grinding, pressing and sintering of the powder 50.0 wt% Fe, 47.0 wt% BaTiO3 and 3.0 wt% TiO2 on morphology, microstructure, magnetic and electric properties [PDF]
Science of SinteringA mixture of 50.0 wt% Fe, 47.0 wt% BaTiO3, and 3.0 wt% TiO2 powders is milled and then pressed and sintered. Samples sintered from ground powders have a structure consisting of plates.
