Electronic structure of Calcium hexaborides

Author(s): Lee, Byounghak; Wang, Lin-Wang | Abstract: We present a theoretical study of crystal and electronic structures of CaB6 within a screened-exchange local density approximation (sX-LDA). Our ab initio total energy calculations show that CaB6 is a semiconductor with a gap of > 1.2 eV, in agreement with recent experimental observations. We show a very sensitive band gap dependence on ...
