1. 1. Semiconductor Quantum Dots Studied by Time-Resolved Luminescence Techniques

   Författare :Jörg Siegert; KTH; []
   Nyckelord :quantum dots; semiconductors; photoluminescence; time-resolved;

   Sammanfattning : In this thesis time-resolved photoluminescence spectroscopyis presented as a powerful tool to study the carrier dynamicsin various self-assembled quantum dot (QD) structures, whichare potentially attractive for device applications. The experiments reveal the impact of proton irradiation onInGaAs QDs and comparable quantum wells. LÄS MER

3. 2. Carrier dynamics in semiconductor quantum dots

   Författare :Jörg Siegert; Ari Friberg; Jesper Mørk; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum dots; photoluminescence; time-resolved; spectroscopy; semiconductor; Optics; Optik;

   Sammanfattning : This thesis presents results of time-resolved photoluminescence experiments conducted on several different self-assembled InGaAs/GaAs and InAs/GaAs semiconductor quantum dot (QD) structures. Depending on the application in mind, different structural, electronic or optical properties have a different weight of importance. LÄS MER
