Kinetic limitation of chemical ordering in Bi${}_2$Te${}_{3-x}$Se${}_x$ layers grown by molecular beam epitaxy

S. Schreyeck, K. Brunner, A. Kirchner +7

We study the chemical ordering in Bi${}_2$Te${}_{3-x}$Se${}_x$ grown by molecular beam epitaxy on Si substrates. We produce films in the full composition range from x = 0 to 3, and deter…
