    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.

  5. 3. Organic electrochemical transistor

    Author : David Nilsson; Xavier Crispin; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Conducting polymers entered the research field in late 70's and investigations regarding printable electronics started a decade later. In this thesis printable organic electrochemical transistors (OECT) will be treated. Conjugated polymers can be switched between a high conducting and low conducting state in electrochemical cells.
