文摘
- •
Single- and polycrystalline samples of RuGa3 were synthesized.
- •
The initial chemical composition is maintained in the samples.
- •
Single crystal X-ray diffraction analysis reveals RuGa3 to be stoichiometric.
- •
Intrinsically, thermal conductivity and thermopower show distinct features below 40 K.
- •
In polycrystalline RuGa3 the pronounced peaks are nearly completely suppressed.
