WebGrowth behaviors of AlN on hexagonal configuration hole-type and truncated-cone-pillar-type nano-patterned sapphire substrates (NPSSs) have been investigated. It is found that threading dislocation density (TDD) of AlN grown on the hole-type NPSS reaches 4.87 × 108 cm−2, which is over one order of magnitude WebActie: Rollen gaas groen of zwart nieuw 100 tot 200 cm hoog.

Web1 apr. 1982 · A high location of the crucible (crystals 40 and 254 G. Jacob ci al. / Dislocations in GaAs 41 in table 1) leads to a difficult control of the shape of the neck, so that only 4 mm diameter necks have been obtained, with sometimes occur- rence of twins (fig. 9). The difficulty in the diame- ter control of the neck and the occurrence of twins is ...
