Fracture toughness of Co4Sb12 and In0.1Co4Sb12 thermoelectric skutterudites evaluated by three methods

► Indium interstitials improve thermoelectric properties of Co4Sb12 skutterudites. ► Fracture toughness is not degraded by indium interstitial doping. ► Indentation fracture toughness test is inaccurate for Co4Sb12 skutterudites. ► Fracture toughness of Co4Sb12 skutterudites is as low as 0.5MPa√m. ►...
