Abstract

We have studied the wurtzite (W)-zinc-blende (ZB) polytypism in ZnSe films grown on the(111)A-orientedsubstrates of GaAs. Although the stable structure of bulk ZnSe is ZB, W-structured ZnSe is formed near the interface on the ZB-structured GaAs(111)A substrate. Our first-principles calculations have revealed that the charge state at the ZnSe/GaAs(111)A interface plays a key role in the formation of W-ZnSe. We show that the structural quality of W-ZnSe is significantly improved using a cracked Se source, while ZB-ZnSe is grown using a vicinal GaAs(111)A substrate.
