Graded InGaN Buffers for Strain Relaxation in GaN/InGaN Epilayers Grown on sapphire
Graded InGaN buffers were employed to relax the strain arising from the lattice and thermal mismatch in GaN/InGaN epilayers grown on sapphire. An enhanced strain relaxation was observed in GaN grown on a stack of five InGaN layers, each 200 nm thick with the In content increased in each layer, and w...
