| 摘要 | This study investigates the optical anisotropy spectrum in the R-plane (i.e., the View the MathML source[101¯2]-oriented layer plane) of GaN/Al0.2Ga0.8N quantum wells of different widths. The optical matrix elements in the wurtzite quantum wells are calculated using the k⋅pk⋅p finite difference scheme. The calculations show that the valence band mixing effect produces giant in-plane optical anisotropy in View the MathML source[101¯2]-oriented GaN/Al0.2Ga0.8N quantum wells with a narrow width. The nature of the in-plane optical anisotropy is found to be dependent on the well width. Specifically, it is found that the anisotropy changes from x′x′-polarization to y′y′-polarization as the well width increases. |
