SDK's SiC epitaxial wafer business is rated by power semiconductor manufacturers for the lowest incidence of
crystal defect and the highest wafer homogeneity in the world.
In the recrystallization process, the residual solvents and bubbles are easily trapped in the crystal to form the
crystal defect, which can increase the SSA of HNS particles.
Conventional LEDs based on foreign substrates like sapphire, silicon carbide, or silicon do have limited reliable operating regimes (typically only up to 85[degrees]C) because of their high
crystal defect densities."

(2) XRD patterns show that sodium doping led to
crystal defect that could make absorption reactivity increase.
However, fine particles of titanium oxide often develop
crystal defect, resulting in lower efficiency in the use of light and lower photocatalytic activity.
These wafers, with high surface smoothness and low
crystal defect, are being produced at SDK's Chichibu Plant in Saitama Prefecture.
Atomic defects in materials such as diamond are one such system, but a lack of techniques for fabricating and engineering
crystal defects at the atomic scale has limited progress to date.
The phenol would be photocatalyzed because more naked Zn atoms on the
crystal defects bind O atoms of phenol molecules.
As MOSFET's oxide film, formed on the surface of an epitaxial wafer, is used in device operations, finer surface defect (SD) and various types of
crystal defects, including basal plane dislocation (BPD), considerably affect the yield and product quality.
