Group III nitride layers have a wide range of uses in electronics and optoelectronics. Such layers are generally grown on substrates such as sapphire, SiC and recently Si(111). For the purpose inter alia of integration with Si-CMOS electronics, growth on Si(001) is indicated, which is possible only with difficulty because of the different symmetries and is currently limited solely to misoriented Si(001) substrates, which restricts the range of use. In addition, the layer quality is not at present equal to that produced on Si(111) material. Growth on exactly oriented Si(001) and an improvement in material quality can now be simply achieved by a modification of the surface structure possible with a plurality of methods.
