Feb 1, 2025 · In this study, we overcame these challenges by replacing pure Tantalum (Ta is stable in crystal structure) with Tantalum-hydride (TaH 2 is relatively unstable in crystal structure) to prepare Ti-Ta alloys using laser additive manufacturing technology.

TaH2 is Fluorite structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ta is bonded in a body-centered cubic geometry to eight equivalent H atoms.

Jul 20, 2022 · Here, we report a bulk vdW material consisting of superconducting 1H TaS 2 monolayers interlayered with 1T TaS 2 monolayers displaying charge density waves (CDW). This bulk vdW heterostructure is created by phase transition of …

The following shows the X-ray diffraction (XRD)[Source-code] pattern and the Radial distribution function (RDF) plots [Source-code]. XRD peaks should be comparable to experiments for bulk structures. Relative intensities may differ.

Mar 17, 2016 · We observe that superconductivity persists down to the thinnest layer investigated (3.5 nm), and interestingly, we find a pronounced enhancement in the critical temperature from 0.5 to 2.2 K as the...

Feb 24, 2017 · We report on the emergence of robust superconducting order in single crystal alloys of TaSe 2− x S x (0 ≤ × ≤ 2). The critical temperature of the alloy is surprisingly higher than that of the...

A pressure–temperature phase diagram of the Ta–H system has been determined using the in situ synchrotron radiation X-ray diffraction technique below 9 GPa and 600 C in this study. At room temperature, the phase boundary obtained between distorted bcc …

Inelastic neutron scattering revealed four vibrational modes in the fundamental band of A15-TaH1.23(5) at 72, 135, 145, and 166 meV, the first three and the last one of which were tentatively assigned to the vibrations of H atoms at the 24k and 16i sites, respectively.

Jul 15, 2020 · TaH2 is Fluorite structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ta is bonded in a body-centered cubic geometry to eight equivalent H atoms.

Series of in situ synchrotron radiation powder X-ray diffraction patterns of Ta and BN powder mixture at 8.17 GPa during heating from 599 °C to 659 °C. Discontinuous lattice expansion was...
