Book excerpt: The dramatic emergence of high brightness blue and green light emitting diodes (LEDs) and blue-violet laser diodes relies on the grown of GaN and related alloys along the polar [0001] direction of the wurtzite crystal structure. Discontinuities in the spontaneous and piezoelectric polarization fields at heterointerfaces in optoelectronic device structures lead to the formation of large internal electric fields (& sim;MV/cm), resulting in a red-shift in the emission wavelength, a decrease in the radiative recombination rate, and a blue-shift in the emission wavelength with increasing drive current. The QCSE may be minimized or eliminated through the growth of GaN orientations inclined with respect to the polar [0001] axis--these growth orientations have been termed semipolar GaN.
