    This Master dissertation explores diffuse reflection spectroscopy as a viable tool for analytical chemistry, both quantitatively and qualitatively. In-vitro optical phantoms are created to mimic the turbid diffuse environments ...
  • Exploring flatland nano-optics with graphene plasmons 

    Woessner, Achim (Universitat Politècnica de Catalunya, 2017-05-11)
    Doctoral thesis
    Open Access
    Plasmons are charge oscillations coupled to electromagnetic radiation. One of their most intriguing properties is their deep subwavelength confinement resulting in strongly enhanced light-matter interaction. Metal plasmons ...
  • Exploring intersubbands in 2D materials 

    Schmidt, Peter, 1989- (Universitat Politècnica de Catalunya, 2019-04-16)
    Doctoral thesis
    Open Access
    Transition metal dichalcogenides (TMDs) are semiconducting layered materials that can be isolated up to the limit of a single atomic layer. Next to graphene, they are some of the most intensively studied materials within ...
  • Fabrication and characterization of graphene nanostructures 

    Navickaite, Gabriele (Universitat Politècnica de Catalunya, 2012-09-06)
    Master thesis
    Open Access
    [ANGLÈS] We fabricate graphene nanostructures for experimental studies on graphene plasmonics and graphene-quantum dot interactions. We use a focused ion beam to mill structures in a substrate, and deposit graphene on top. ...
