Formation and Optical Properties of BaSi2 Films on Si (111) – a Promising Nanomaterial for Solar Cells

Abstract

Nowadays, scientists investigate new more efficient materials for creating solar cells. One of such materials is thin films of barium disilicide. In this paper, we describe formation of BaSi2 films on Si(111) by layer-by-layer solid phase epitaxy and study their optical properties in visible and infrared range.
