Electrical properties as a function of temperature.
(a) Electrical resistivity, (b) thermopower, (c) carrier concentration and (d) carrier mobility of YbxGa0.2Co4Sb11.9333 (x = 0, 0.05, 0.10, 0.15, 0.20, 0.26), YbyGa0.15Co4Sb11.95 (y = 0.25, 0.30, 0.35, 0.40), Yb0.20GazCo4Sb12-z/3 (z = 0, 0.10, 0.15) and Yb0.26Co4Sb12. The dashed line in (d) represents the temperature dependence of T−3/2, indicating an acoustic phonon scattering trend line for eye guidance.
