dc.description.abstract | We study an electronic structure of CeRhSb1xSnx system, which displays quantum critical
transition from a Kondo insulator to a non-Fermi liquid at x = 0:13. We provide ultraviolet photoelectron
spectra of valence band obtained at 12.5 K. A coherent peak at the Fermi level is not present in the data,
but a signal related to 4f1
7=2 nal state is detected. Spectral intensity at the Fermi edge has a general
tendency to grow with Sn content. Theoretical calculations of band structure are realized with full-potential
local-orbital minimum-basis code using scalar relativistic and full relativistic approach. The calculations
reveal a depletion of density of states at the Fermi level for CeRhSb. This gap is shifted above the Fermi
energy with increasing Sn content and thus a rise of density of states at the Fermi level is re
ected in
the calculations. It agrees with metallic properties of compounds with larger x. The calculations also yield
another important e ect of Sn substitution. Band structure is displaced in a direction corresponding to hole
doping, although with deviations from a rigid band shift scenario. Lifshitz transitions modify a topology
of the Fermi surface a few times and a number of bands crossing the Fermi level increases. | pl_PL |
