Abstract

The crystal structure of beta-rhombohedral boron is composed of B₁₂ ICOSAHEDRAL CLUSTERS WITH THREE KINDS OF INTERSTICES A₁, D, E which are large enough to accomondate transition metals. Transition metals occupy the intersticies alternatively. The properties arised by interactions between doped atoms via B₁₂ clusters are an issue of interest. In this study, we successfully synthesized Fe and Cu-codoped beta-boron by solid state reaction.
