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

5. Influence of intermolecular order at the interfaces
Abstract : The work presented in this thesis covers a range of different surfaces and interfaces of organic molecules/polymers and metallic materials. It is of vita importance to understand how charge transfer processes and other electrical interactions existing at physisorped contacts can influence the electronic structure at an interface.
