  7. 5. Optics of Conducting Polymer Thin Films and Nanostructures

    Författare :Shangzhi Chen; Magnus Jonsson; Vanya Darakchieva; William Barnes; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Intrinsically conducting polymers forms a category of doped conjugated polymers that can conduct electricity. Since their discovery in the late 1970s, they have been widely applied in many fields, ranging from optoelectronic devices to biosensors. The most common type of conducting polymers is poly(3,4-ethylenedioxythiophene), or PEDOT. LÄS MER
