[11p-W834-12] Electronic Structure of Zintl-Phase Solar-Cell Material BaSi2

〇Motoharu Imai1 (1.NIMS)

Keywords:barium disilicide, solar-cell material, Zintl phase

We calculated the electronic structure of P4 tetrahedron, Si4 tetrahedron, the hypothetical material 4Si4 which was formed by removing Ba atoms from BaSi2, and BaSi2. Using these results, we will discuss how to construct the electronic structure of BaSi2.
