Abstract(in English) InGaN quantum wells (QWs) grown on three dimensionally (3D) structured GaN are promising for phosphor-free white LEDs. However, previously reported structures have a problem that In-rich InGaN QWs for longer wavelength emission are fabricated on the (0001) polar plane, where the optical transition probability is low due to the strain-induced piezoelectric fields. In this study, we demonstrate that polar-plane-free 3D QWs, which possess highly efficient polychromatic emission properties, can be fabricated on (-1-12-2) semipolar GaN substrates. Furthermore, white color synthesis using the polar-plane-free structure is also demonstrated.
