Visible emission spectroscopy of highly charged tungsten ions in LHD: II. Evaluation of tungsten ion temperature [PDF]
Phys. Scr. 90 (2015) 125403 (7pp), 2020 We demonstrated a polarization-resolved high resolution spectroscopy of a visible emission line of highly charged tungsten ions ({\lambda}0 = 668.899 nm, Shinohara et al Phys. Scr. 90 125402) for the large helical device (LHD) plasma, where the tungsten ions were introduced by a pellet injection.

Deuterium retention in tungsten fiber-reinforced tungsten composites [PDF]
Nuclear Materials and Energy, 2021 In future fusion reactors, plasma-facing materials (PFMs) have to withstand unique conditions such as high temperatures, ion and neutron irradiation. Tungsten (W) has been established as main candidate material due to its favorable properties regarding the fusion environment but brings one major challenge: Its brittleness at moderate temperatures can ...

Stress Analysis of Tungsten Deposition in a 3D Trench Mold With Regard to Initial Nuclei Shape
IEEE Access, 2022 Tungsten has been commonly used for fine interconnects due to its good gap-filling characteristics in 3D molds, such as trench patterns. However, tungsten shows high deposition stress. This causes mold distortion because tungsten has low ad-atom mobility,

On local sensing of spin Hall effect in tungsten films by using STM-based measurements [PDF]
, 2017 The spin Hall effect in tungsten films has been experimentally studied by using STM-based measurements. These measurements have been performed by using tungsten and iron coated tungsten tips. In the case of tungsten tips, it has been observed that the current flow through the tungsten film results in an appreciable asymmetry in the tunneling current ...

Large remnant polarization and great reliability characteristics in W/HZO/W ferroelectric capacitors
Frontiers in Materials, 2022 In this work, the effect of rapid thermal annealing (RTA) temperature on the ferroelectric polarization in zirconium-doped hafnium oxide (HZO) was studied. To maximize remnant polarization (2Pr), in-plane tensile stress was induced by tungsten electrodes

Electrodialytic removal of tungsten and arsenic from secondary mine resources: Deep eutectic solvents enhancement [PDF]
, 2020 Tungsten is a critical raw material for European and U.S. economies. Tungsten mine residues, usually considered an environmental burden due to e.g. arsenic content, are also secondary tungsten resources. The electrodialytic (ED) process and deep eutectic solvents (DES) have been successfully and independently applied for the extraction of metals ...

On the miscibility gap in tungsten-based alloys [PDF]
arXiv, 2023 In this work we establish an approach to model miscibility gaps of alloys using statistical physics, lattice dynamics from first-principles calculations. We carefully calculate the entropy to include all processes introducing disorder to the system, i.e., combining the electronic, phononic, and configuration entropies.
