| To prove it, the researchers first measured the specific heat of both the unfilled and filled skutterudite. |
| Thermodynamically metastable skutterudite crystalline-structured compounds are disclosed having preselected stoichiometric compositions. |
| The name skutterudite comes from the locality of Skutterud, Norway. |
| The crystal is a combination of antimony and cobalt known as a skutterudite. |
| We present evidence of a relatively high dimensionless figure of merit in a polycrystalline skutterudite partially filled with ytterbium ions. |
| Putting atoms of another element in the skutterudite voids makes the materials more glass-like. |
