Vertical Silicon Nanowires for Image Sensor Applications
Conventional image sensors achieve color imaging using absorptive organic dye filters. These face considerable challenges however in the trend toward ever higher pixel densities and advanced imaging methods such as ...
Carbon Nanotubes for the Generation and Imaging of Interacting 1D States of Matter
Low-dimensional systems in condensed matter physics exhibit a rich array of correlated electronic phases. One-dimensional systems stand out in this regard. Electrons cannot avoid each other in 1D, enhancing the effects of ...
Femtosecond laser direct writing of 3D metallic structures and 2D graphite
This thesis explores a novel methodology to fabricate three dimensional (3D) metal-dielectric structures, and two dimensional (2D) graphite layers for emerging metamaterials and graphene applications. The investigations ...
Plasmonics for surface-enhanced Raman scattering: from classical to quantum
Metallic nanostructures that employ localized surface plasmon resonances to capture or radiate electromagnetic waves at optical frequencies are termed "plasmonic optical antennas". These structures enhance light-matter ...
Two-Dimensional Plasmonics in Massive and Massless Electron Gases
Plasmonic waves in solid-state are caused by collective oscillation of mobile charges inside or at the surface of conductors. In particular, surface plasmonic waves propagating at the skin of metals have recently attracted ...
