1. ON THE COUPLING OF THE LOCALIZED PLASMON AND INTERBAND TRANSITIONS IN NICKEL NANOANTENNAS
Abstract : Interaction of light with metallic nanostructures smaller than the wavelength leads to excitation of collective oscillations of “free” conduction electrons. This effect leads to locally enhanced electric fields inside and outside the nanoparticle and is called localized surface plasmon resonance (LSPR). READ MORE

3. InGaAs-based quantum dots for infrared imaging applications : growth and characterisation
Abstract : In this thesis, results are presented from the development of quantum dot (QD) based infrared photodetectors (IPs). This includes epitaxial growth of QDs, investigations of the structural, optical and electronic properties of the QD based material as well as characterisation of the resulting components. READ MORE

4. Spectroscopic studies of doped GaAs/ AlGaAs quantum wells in the high carrier density regime
Abstract : This thesis is mainly based on experimental and theoretical investigations of the electronic structures and optical properties of p-type doped GaAs/AlGaAs quantum wells using a combination of photoluminescence and magneto-optical spectroscopy in the presence of high magnetic fields.The effects of high hole densities up to 3.
