A big challenge: The experimental electron density of CoSb3 was determined based on short-wavelength single-crystal synchrotron data (10 K), thereby giving a view of covalently bonded Co and Sb atoms that carry only small negative and positive charges, respectively. This result contradicts the conventional view of the electrostatic properties of the structure used in thermoelectric studies.
