  2. 1. Optical Characterization and Optimization of Display Components : Some Applications to Liquid-Crystal-Based and Electrochromics-Based Devices

    Author : Iryna Valyukh; Claes-Göran Granqvist; Ewa Wäckelgård; Hans Arwin; Ola Hundery; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ellipsometry; liquid crystal; LCD; optical anizotropy; electrochromic; inverse problems; Optics; Optik; Optical physics; Optisk fysik; Numerical analysis; Numerisk analys; Solid State Physics; fasta tillståndets fysik; Information Systems; data- och systemvetenskap;

    Abstract : This dissertation is focused on theoretical and experimental studies of optical properties of materials and multilayer structures composing liquid crystal displays (LCDs) and electrochromic (EC) devices. By applying spectroscopic ellipsometry, we have determined the optical constants of thin films of electrochromic tungsten oxide (WOx) and nickel oxide (NiOy), the films’ thickness and roughness.

  4. 2. Heat Transport from On-demand Single-Electron Sources

    Author : Nastaran Dashti; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluctuations and noise; thermoelectric devices; energy-selective detector; single-electron source; charge and heat currents;

    Abstract : The controlled injection of quantized charge excitations from single-electron emitters into nanoscopic conductors sets the basis for many important applications ranging from metrology to the emerging field of quantum optics with electrons. Successful implementation of these applications relies not only on achieving control on the precision of the particle emission, but also on the energetic properties of the injected particles.
