In particular, provided is a silicon carbide single crystal substrate that is a substrate cut from a bulk silicon carbide single crystal grown by the Physical Vapior Transport (PVT) method, in which the screw dislocation density is smaller in the peripheral region than in the center region, so that screw dislocations are partially reduced.The method is a method for manufacturing a SiC single crystal by the PVT method using a seed crystal and the ingot is a SiC single crystal ingot obtained by the method. Particularly, the silicon carbide single crystal substrate is a silicon carbide single crystal substrate in which when, by representing the diameter of the substrate as R, a center circle region having a diameter of 0.5×R centered around a center point O of the substrate and a doughnut-shaped peripheral region remaining by excluding the center circle region are defined, the average value of screw dislocation densities observed in the doughnut-shaped peripheral region is 80% or less of the average value of screw dislocation densities observed in the center circle region.

    摘要: A liquid crystal optical element having a crystal liquid optical element adapted to positively function as a diffraction element and an optical pickup apparatus including the liquid crystal optical element are disclosed. A transparent electrode having a diffraction pattern is arranged on one of a pair of transparent substrates. A liquid crystal panel has a transparent opposed electrode arranged on the other one of the pair of the transparent substrates. A driving unit generates a phase difference distribution in the liquid crystal layer by generating a potential difference between the transparent electrode and the transparent opposed electrode and causes the liquid crystal panel to function as a diffraction element for diffracting the incoming light beam transmitted therethrough. The diffraction pattern or the transparent opposed electrode is divided into a plurality of regions. The driving unit adjusts the potential difference for each of the regions.
