Low-temperature synthesis of hydride semiconductor YH3−δ using Pt capped Y films and its chemical thermodynamics analysis

Lattice dynamic stability and electronic structures of ternary hydrides La1−xYxH3via first-principles cluster expansion

“…Hydrogen-rich materials have attracted considerable attention thanks to their potential applications, especially in hydrogen storage, [1][2][3] as well as the changes in physical and chemical properties as a function of the hydrogen concentration. [4][5][6][7][8] The electronic structures of several rare-earth hydrides have been widely investigated, [9][10][11][12][13][14][15][16][17] for example, the metal-semiconductor transition in lanthanum dihydride and lanthanum trihydride. 9 Also, lanthanum deuterium was observed by neutron diffraction measurements 18 to form NaCl-type LaD at high pressures as a result of pressure-induced decomposition of LaH 2.3 via dismutation.…”
