Abstract
⺠The morphology of GaN etched in hydrogen at different temperatures is studied. ⺠H2 etching has controllable etching directions. ⺠The activation energy of the rate-limiting step of hydrogen etching is 3.7 eV. ⺠A 320 μm-thick GaN layer has self-separated from the underlying sapphire substrate.
