We applied the Perdew-Burke-Ernzerhof hybrid functional (PBE0) within the density functional theory (DFT) to study electronic properties of the heavy fermion Kondo semiconductor SmB_{6}. The calculation of the Hartee-Fock exchange contribution to the exact-exchange within the atomic sphere approximation for bulk SmB_{6} represents a computationally efficient, parameter-free method that provides good...
The thermoelectric power was measured from 4.2 to 300 K for CeNi_4Si and YbNi_4Si. The thermoelectric power was analysed in the framework of the phenomenological resonance model. According to the model the dominant contribution to thermopower is caused by scattering between electrons of a broad s-band and a narrow f-band with the Lorentzian shape. The electron-hole analogy is reflected in the thermoelectric...
