Different evolution of the intrinsic gap in strongly correlated SmB sub(6) in contrast to YbB sub(12)

Dependence of the spectral functions near the Fermi level on temperature and rare-earth atom doping was studied in detail for strongly correlated alloys Sm sub(1-x)Eu sub(x)B sub(6) and Yb sub(1-x)Lu sub(x)B sub(12) by photoelectron spectroscopy at ~8000 eV as well as at 7 and 8.4 eV. It was found t...
