Hydrogen in actinides: electronic and lattice properties

Popis výsledku v původním jazyce

Hydrides of actinides, their magnetic, electronic, transport, and thermodynamic properties are discussed within a general framework of hydrogen impact on bonding, characterized by volume expansion, and a charge transfer towards hydrogen. These general mechanisms have diverse impact on individual actinides, depending on the degree of localization of their 5f states. Ab-initio computational analyses are corroborated by spectroscopic studies of sputter-deposited thin films, yielding a clean surface and offering a variability of compositions. It is found that valence-band photoelectron spectra cannot be compared directly with the ground-state density of states. Being affected by electron correlations in the excited final states, they rather reflect the atomic multiplets. Similar tendencies can be identified also in hydrides of binary and ternary intermetallic compounds. A new direction is represented by actinide polyhydrides with a potential for high-temperature superconductivity.n
