Abstract
In order to drop the dislocation density and reduce the manufacturing costs, GaN can be deposited on substrates that possess a high density of growth sites. In our present strategy, we simultaneously focus on overcoming the misorientation and dislocation problems. To achieve this goal, nanopatterning of GaN/AlN layers deposited on Silicon-On-Insulator (SOI) substrates is used in order to fabricate nanopillar arrays, using nanoimprint lithography (NIL) and plasma etching. This will be reflected by the high-quality epitaxial layer of GaN. The latter will be used as an active layer to produce a LED array having a better emission quality.
