摘要： A method of making a conductive group III nitride single crystal substrate includes feeding to a seed crystal a group III raw material gas, a group V raw material gas, and a doping raw material gas diluted with N2 or Ar to have a predetermined concentration, growing a group III nitride single crystal on the seed crystal at a growth rate of greater than 450 μm/hour and not greater than 2 mm/hour, and doping the group III nitride single crystal with an impurity contained in the doping raw material gas. The doping raw material gas is diluted to be inhibited from reacting with the group V raw material gas so as to allow the group III nitride single crystal to have a specific resistance of not less than 1×10−3 Ωcm and not more than 1×10−2 Ωcm.

摘要： A dispersion element includes a prism having a first transmission surface and an oppositely disposed second transmission surface, and an optical element having a third transmission surface and an oppositely disposed diffraction optical surface on which a diffraction grating is arranged. The prism and the optical element are integrated into one body by cementing the first transmission surface to the third transmission surface. The third transmission surface and the diffraction optical surface are non-parallel to each other in a plane perpendicular to grooves of the diffraction grating.
