2. Optical Studies of Single Quantum Dots
Abstract : This thesis presents spectroscopic studies of single self-assembled InP quantum dots (QDs). The electronic properties of these QDs have been studied by photoluminescence (PL) and scanning tunnelling luminescence (STL). The QDs were grown in the Stranski-Krastanow mode and were embedded in GaInP. READ MORE
