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

    Författare :David Nilsson; Magnus Berggren; George G. Malliaras; Linköpings universitet; []
    Nyckelord :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.

  4. 3. CdTe detectors and the Mössbauer effect in ¹²⁵Te : investigations for an axion search

    Författare :Lars Mårtensson; Bo Cederwall; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Sammanfattning : The use of CdTe crystals as radiation detectors is hampered by the drift properties of charge carriers in CdTe, that make the response depend on the interaction point in the detector crystal. To remedy these effects a detailed model of the signal formation process in such detectors was developed and fitted to sampled pulse shapes. LÄS MER

  5. 4. Organic electrochemical transistor

    Författare :David Nilsson; Xavier Crispin; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : 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.
