4. Implantation isolation in AlGaAs/GaAs structures
University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)Abstract : In this work the effect of implantation isolation in vertical cavity surface emitting laser (VCSEL) samples have been investigated cross sectional measurements using scanning spreading resistance microscopy (SSRM). The samples consist of two AlGaAs/GaAs Distributed Bragg Reflectors (DBR) structures with a GaAs quantum well region sandwiched in between them. READ MORE
