Imma-B60 exhibits a narrow bandgap (<0.2 eV) with a conductivity of ~9 × 102 S m−1, seven orders of magnitude higher than β-boron.",

The reported conductivity and narrow gap refer to synthesized Imma-B60 after sodium degassing; supplementary measurements average three independent samples and distinguish measured electrical gap from calculated band structures."
