Thin films of the layered chalcogenide GaSe were deposited on Si(111), Si(1
10), and Si(100) surfaces by molecular beam epitaxy. The interface formatio
n was investigated with photoemission and LEED. In all cases GaSe grows wit
h its hexagonal (0001) axis normal to the substrate surfaces. (C) 2000 Else
