Dalton Trans., 2014, Advance Article
DOI: 10.1039/C4DT01303D, PaperTakao Mori, Toshiyuki Nishimura, Walter Schnelle, Ulrich Burkhardt, Yuri Grin
It was revealed that boron carbide inclusions were the origin of the p-type behavior in the Seebeck coefficient [small alpha] previously observed for Y1-xB28.5C4 in contrast to Y1-xB15.5CN and Y1-xB22C2N, the long awaited n-type counterparts to boron carbide. Calculations show a pseudo gap-like structure in density of states and importance of the borocarbonitride network.
