  1. 1. Flexible and Cellulose-based Organic Electronics

    Författare :Jesper Edberg; Magnus Berggren; Isak Engquist; Leif Nyholm; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; conductive polymers; nanocellulose; nanofibrillated cellulose; composite materials; paper electronics; flexible electronics;

    Sammanfattning : Organic electronics is the study of organic materials with electronic functionality and the applications of such materials. In the 1970s, the discovery that polymers can be made electrically conductive led to an explosion within this field which has continued to grow year by year. LÄS MER

  2. 2. Electrolyte-Gated Organic Thin-Film Transistors

    Författare :Lars Herlogsson; Magnus Berggren; Hagen Klauk; Linköpings universitet; []

    Sammanfattning : This thesis focuses on the chemical concept of conjugation, i.e., electron delocalization, and the effect it has on electronic and optical properties of molecules. LÄS MER

  5. 5. An Organic Electrochemical Transistor for Printed Sensors and Logic

    Författare :David Nilsson; Magnus Berggren; George G. Malliaras; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; printable organic electrochemical transistors OECT ; polymers; charge signal carriers; proton-conducting electrolyte Nafion ; Organic chemistry; Organisk kemi;

    Sammanfattning : Conducting polymers entered the research field in late 70´s and efforts aimed at achieving printed electronics started a decade later. This thesis treats printable organic electrochemical transistors (OECT). Some conjugated polymers can be switched between a high conducting and a low conducting state in an electrochemical cell.
