Low temperature thermoelectric power of amorphous alloys Al-Y-Ni

Low temperature thermoelectric power of amorphous alloys Al_90-xY₁₀Ni_x (x=0,2,5 and 8) exhibits the characteristic “knee” which is related to the electron-phonon mass enhancement. The Debye temperature T_D and the electron phonon mass enhancement parameter determined from the experimental data diminish with the rising Al content. This surprising observation suggests the reduction of the density of states at the Fermi level related to the attractive bonding force Al-Y which affects the nanocrystallization processes
