Abstract
Optimized extended-InGaAs photodetectors were grown on InP substrate using metamorphic buffer layers to achieve a strain relaxation. The samples were investigated by transmission electron microscopy and X-Ray diffraction. The results show that a number of metamorphic buffer layers and their thickness play an important role in material quality and photodetectors performance.
