Abstract

Highly oriented strontium oxide (SrO) whiskers were obtained using a chemical vapor deposition technique at atmospheric pressure. The SrO whiskers were synthesized on a single-crystalline Si(100) substrate from strontium bis-dipivaloylmethanate, Sr(C11H19O2)2. The presence of face-centered cubic (fcc) SrO structures was confirmed. The hexagonal SrO whiskers were preferentially oriented in the <111> direction upon increasing deposition time. This phenomenon is based on equilibrium figure in the <111> direction of fcc crystals.
