grown on the carbonized Si111 substrate has much narrower full width at half maximum of the X-ray rocking curve and almost
one order higher intensity in the photoluminescence emission than that directly grown on the Si substrate and the carbonized
Si100 substrate. According to the characterization of the two kinds of carbonized Si substrates and the epitaxial models, the
improvement of the ZnO film grown on the carbonized Si111 substrate was attributed to the reduced lattice mismatch by placing
a 111-oriented 3C-SiC buffer layer. In contrast, ZnO film grown on the carbonized Si100 substrate exhibited an increased
lattice mismatch by placing a 100-oriented 3C-SiC buffer layer. This resulted in the poor quality of the ZnO overgrown layer.
Moreover, using optimized growth conditions, a high-quality ZnO film was prepared on the carbonized Si111 substrate.详细>
