Structural changes to epitaxial (0001) holmium layers during hydrogen loading

Abstract:

HoHy exhibits dramatic changes in both structural and optical properties as y is varied from zero to three by hydrogen loading. This work reports on the effect of such loading upon epitaxial single-crystal Ho films grown by molecular beam epitaxy on (110) Nb∥(112̄0) Al2O3 substrates. Upon loading, the film undergoes a structural transition from hcp metal (α-phase, H in solid solution) to the fcc dihydride (β-phase). There is a further transformation between the dihydride phase and the hexagon...
