| Abstract(in English) | We have investigated dislocations in GaN-based laser diodes (LDs) on epitaxial lateral overgrown (ELO) GaN layers using transmission electron microscopy and cathodoluminescnce microscopy and found a correlation between dislocations and device reliability. The origin of dislocations in the wing regions of ELO structures is the extension of defects in highly defective regions near the GaN layer/substrate interface of the seed regions. In some LDs with a short lifetime, dislocations lying in the c-plane were formed below the active regions, bent towards the c-axis and threaded upwards to active regions. These newly created dislocations can cause to be detrimental to the device lifetime. |
