  1. 1. Organic electrochemical transistor

    Författare :David Nilsson; Xavier Crispin; Linköpings universitet; []

    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.

  2. 2. Analog Circuit Topology Development: Practice methods for technology and teaching based on comprehensible transistor models

    Författare :Roger Malmberg; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; episteme; analog design; circuit synthesis; field-effect transistor; teaching method; phronesis; techne; bipolar transistor; transistor model;

    Sammanfattning : To obtain adequate knowledge for design of robust analog circuits in industry, circuit engineers gain main knowledge from own practice experience, because theory taught by universities rarely states validity limits and result spreads. Therefore, when going from university to industry, the engineers find this theory nontrustworthy and relinquish it. LÄS MER

  3. 3. Vertical III-V Nanowire Tunnel Field-Effect Transistor

    Författare :Elvedin Memisevic; Nanoelektronik; []
    Nyckelord :Transistor; TFET; Steep slope; Nanowire; III-V materials; HSQ; Vertical; InAs; GaSb; MOSFET;

    Sammanfattning : In this thesis fabrication and optimization of vertical III-V Tunneling Field-Effect transistors was explored. Usage of vertical nanowires, allows for combination of materials with large lattice mismatch in the same nanowire structure. LÄS MER

  4. 4. Noise Properties of the Single Electron Transistor

    Författare :Serguei Kafanov; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Low-Frequency noise; Shot Noise; 1 f noise; Single Electron Transistor; charge sensitivity; SET; electrometer; Coulomb blockade; radio-frequency Single Electron Transistor; RF-SET;

    Sammanfattning : The Single Electron Transistor (SET) is a sensitive electrometer with a charge sensitivityultimately limited by noise. In this thesis we present measurements of noiseproperties and charge sensitivity of the radio-frequency Single Electron Transistor. LÄS MER

  5. 5. InAs Nanowire Devices and Circuits

    Författare :Kristofer Jansson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modelling; Circuit; Simulation; Ballistic; Capacitor; Transistor; RF; Band structure; III-V semiconductor; InAs; MOSFET; Metal-oxide-semiconductor field-effect transistor; Nanowire; Amplifier;

    Sammanfattning : Since the introduction of the transistor and the integrated circuit, the semiconductor industry has developed at a remarkable pace. By continuously fabricating smaller and faster transistors, it has been possible to maintain an exponential increase in performance, a phenomenon famously described by Moore’s Law. LÄS MER
