Abstract
A surface of a substrate consists of a plurality of neighboring stripes. Longer edges of the flat surfaces are parallel one to another and planes of these surfaces are disoriented relatively to the crystallographic plane of gallium nitride crystal defined by Miller-Bravais indices (0001), (11-22) or (11-20). The disorientation angle of each of the flat surfaces is between 0 and 3 degrees and is different for each pair of neighboring flat surfaces. The substrate according to the invention allows epitaxial growth of a layered AlInGaN structure by a MOCVD or MBE method which allow to obtain a non-absorbing mirrors laser diode emitting a light in the wavelength from 380 to 550 nm.
