Preparation and Properties of Scandium Dihydride

Isotope effect in the resistivity of scandium hydride

“…Gravimetric analysis of representative samples of the hydride indicated a stoichiometry of the final products given by SCH1.98±0.02. X-ray analysis of Sell 2 showed a face-centered-cubic lattice with lattice parameter 4.783 -+ 0.001 A, in excellent agreement with previous determinations [3,4]. Apart from two very weak extra lines in the X-ray patterns which indicate the presence of a few percent of Sc203 in the samples, all diffraction lines were due to ScH 2.…”

“…We suspected that electron scattering from these Einstein modes would also be evident in the electrical resistivities of transition metal hydrides. We chose to work with the isoelectronic, iso-structural pair ScH 2 and SoD 2, since they are easily prepared [3] and there are no competing higher hydrides of Sc [3,4].…”

Electrical and Reliability Perspectives for Self-Forming Barrier CuSc Metallization

“…Additionally, its major application is on aluminum alloys with providing positive effects. 12,13 Therefore, Sc was proposed to add in Cu to form CuSc alloys. This is the first time to apply CuSc alloys to BEOL interconnects of ICs.…”

The synthesis and some physical properties of reduced scandium chloride, bromide, and iodide phases with unusual stoichiometries

“…If an ionic diiodlde did not result, it was thought Prom other scandium compounds there is no evidence for stable divalent scandium ion. The ScS (21) is metallic as is ScHg (22). A report of the preparation of ScO (23) from…”
