    Li, Guodong; An, Qi; Li, Wenjuan; Goddard III, William A.; Zhai, Pengcheng; Zhang, Qingjie; Snyder, G. Jeffrey (American Chemical Society, 2015)
    Skutterudites based on CoSb3 have high thermoelectric efficiency, but the low fracture strength is a serious consideration for commercial applications. To understand the origin of the brittleness in CoSb3, we examine the ...
