Abstract
The availability of GaN substrates is crucial for GaN-based laser diodes. Also high performance LEDs ask for high quality substrates. Methods for growth of bulk GaN are reviewed with a focus on hydride vapour phase epitaxy (HVPE), which currently is the method used for the production of GaN substrates. Also the ammonothermal approach is briefly discussed. Both approaches still have to overcome limitations before mass-production at affordable prices is feasible. These limitations are related to the maximum growth rate yielding high quality material as well as the boule length that can be achieved together with high material quality.
