ABSTRACT
A thin silicon nano-overlayer (SNOL) fabricated by oxidation and etchback in a separation by implantation of oxygen wafer was investigated by grazing incident x-ray diffraction at incident angles between 0.01° and 0.1° below the critical angle of total reflection (0.18° ). We measured {220} reflections by probing the sample in depth and found that the SNOL has finite domains under strain close to the surface. We also found that annealing the sample up to 1000 °C significantly reduced inhomogeneous in depth strain and increased the size of the domains in the surface region of the SNOL.
