“…Above the 20 bands, an energy gap of about 0.4 eV is observed, which allows classifying the system as a narrow band semiconductor. Our result is in agreement with previous band structure calculations [26][27][28] as well as the electron transport measurements [29,30], revealing both the semiconducting-like character of the temperature-dependent resistivity as well as a large thermopower.…”

“…FeSi, RuSi and OsSi are well known such compounds with narrow band gap [1,2]. FeSi has a nonmagnetic ground state and exhibits a metallic behavior above 500 K, while shows a large Pauli paramagnetic susceptibility with a pronounced temperature dependence [3]. The band gap of FeSi at low temperature has been confirmed by the experimental measurement of optical reflectivity and tunneling spectroscopy [4], and also the theoretical band calculations [5,6].…”

We present magnetization, specific heat, resistivity, and Hall effect measurements on the cubic B20 phase of MnGe and CoGe and compare to measurements of isostructural FeGe and electronic-structure calculations. In MnGe, we observe a transition to a magnetic state at T c = 275 K as identified by a sharp peak in the ac magnetic susceptibility, as well as second phase transition at lower temperature that becomes apparent only at finite magnetic field. We discover two phase transitions in the specific heat at temperatures much below the Curie temperature, one of which we associate with changes to the magnetic structure. A magnetic field reduces the temperature of this transition which corresponds closely to the sharp peak observed in the ac susceptibility at fields above 5 kOe. The second of these transitions is not affected by the application of field and has no signature in the magnetic properties or our crystal-structure parameters. Transport measurements indicate that MnGe is metallic with a negative magnetoresistance similar to that seen in isostructural FeGe and MnSi. Hall effect measurements reveal a carrier concentration of about 0.5 carriers per formula unit, also similar to that found in FeGe and MnSi. CoGe is shown to be a low carrier density metal with a very small, nearly temperature-independent diamagnetic susceptibility.
