  5. 3. Electrical properties of polycrystalline silicon

    Author : Matts Rydberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Elektronik; Electronics;

    Abstract : Polysilicon is used, among other materials, in today's integrated circuits. In this thesis, the structural and electrical properties' of polysilicon thin film resistors have been studied. The aim has been to improve the long-term stability and increase the knowledge concerning grain-boundary related phenomena. READ MORE

  6. 4. Modelling electrical properties of composite materials

    Author : Eva Mårtensson; KTH; []
    Keywords : ;

    Abstract : Composite field grading materials are used to avoid stressconcentrations in high voltage applications such as cableaccessories and generator or motor end windings. The compositematerials consist of an insulating matrix filled with suitableconducting or semi-conducting particles. Silicon carbide (SiC)powder is one such filler that is being employed. READ MORE

  7. 5. Mechanical and Electrical Properties of Mesoscopic Wires

    Author : Sara Blom; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rabi oscillations; conductance quantization; free electron model; mesoscopic; microwave; channel; force fluctuations; adiabatic; nanowire;

    Abstract : The mechanical and electrical properties of mesoscopic wires have been studied theoretically using a free electron model. When a mesoscopic wire is elongated the conductance decreases in steps. Each step is accompanied by an abrupt change in the force. READ MORE
