Abstract (in Japanese) (See Japanese page) 
(in English) The top of the valence band structure in Wurtzite crystals is split to the irreducible representation of Γ1 and Γ5
by the crystal-field interaction. In the case of AlN, the energetic deference between Γ1 and Γ5 by this interaction are so large
that the strain-induced effects between them may be neglected. Therefore, the strain-induced effects on the eigenstate of Γ1
can be described by two of the deformation potentials. In previous studies, these values have been experimentally determined
in the framework of the quasicubic approximation. In this study, we determined two of the deformation potentials in AlN
without the quasicubic approximation by reflectance spectroscopy under uniaxial stress.
