Abstract

It was revealed that boron carbide inclusions were the origin of the p-type behavior in the Seebeck coefficient α previously observed for Y_1−xB_28.5C₄ in contrast to Y_1−xB_15.5CN and Y_1−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.
