1. 1. Numerical simulations of ultrafast dynamics in plasmonic nanostructures

   University essay from Umeå universitet/Institutionen för fysik

   Author : Nils Henriksson; [2023]
   Keywords : Ultrafast nanophotonics; Three temperature model; Numerical simulations;

   Abstract : Plasmonic effects in nanosized particles enhance the interaction between light and matter due to the localized surface plasmon resonance, with potential applications such as all-optical transistors and optical computers. Commonly, the dynamics of nanoparticles’ optical properties are assessed via pump-probe spectroscopy, where a plasmonic structure is exited by an initial laser, the pump. READ MORE

3. 2. Fabrication and Optimization of a Nanoplasmonic Chip for Diagnostics

   Abstract : The presented project explores the optical properties of magnetoplasmonic Au/Ni core-shell structures. The work aims at controlling dimensions and parameters in order to influence and analyze the optical properties of the nanostructures. The softwares utilized for the simulations were COMSOL Multiphysics 5.1 and MATLAB. READ MORE

5. 4. Patterned Nanocomposite of Carbon Nanotube/Polymer

   University essay from Umeå universitet/Institutionen för fysik

   Author : Saeed Motaragheb Jafarpour; [2017]
   Keywords : ;

   Abstract : Single walled carbon nanotubes (SWCNTs) are carbon based nanostructures with extraordinary electronical and mechanical properties. They are used in a wide range of applications, usually embedded in polymer as fillers to form polymer based nanocomposites, in order to affect the electronic behavior of the polymer matrix.

6. 5. Evaluation of Atomic Layer Etching Possibility at Lund Nano Lab

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Md Sabbir Ahmed Khan; [2016]
   Keywords : Atomic Layer Etching; Nanoimprint lithography; Nanowires; Physics and Astronomy;

   Abstract : In modern electronics, device downscaling demands atomic precision control and Atomic Layer Etching (ALE) can provide this prime capability with minute device damage. ALE, also known as layer-by-layer etching, is a technique of removing atomically thin layers from the surface of materials in a controlled way. READ MORE
