We measured the electrical conductivity to confirm these predictions and further corroborate the match between experiment and calculations. Using the AMSET package , we predicted the conductivity would be 22.2 S/cm at 28.4°C using the band structure of Sc2C. We performed conductivity measurements at the same temperature, where we used a well-insulated system to accurately measure temperature. We found that the conductivity was 1.62 S/cm, which is an order of magnitude smaller than the value we calculated; however, we expect the calculation to overestimate the conductivity because it does not include impurities in the crystal, which are present in experiment. This conductivity confirms that the synthesized material is indeed a semiconductor with a small band gap.
