    Sammanfattning : The industrial development of metal cutting processes in gear manufacturing aims at continuously increasing productivity, including increased tool reliability. Basically, the parameters that have an influence on the cutting processes should be known and possible to control.Gear manufacturing is highly important for the automotive industry. LÄS MER

  7. 25. Processing and characterization of thin film field effect gas sensors

    Författare :Anna Elisabeth Åbom; Linköpings universitet; []
    Nyckelord :MISFET; Field effect chemical gas sensors; long-term stability; sputtering; Pt; TiN;

    Sammanfattning : At Applied Physics, Linköping University, the main interest for sensor research has been the focused on MISFET (Metal-Insulator-Semiconductor Field-Effect Transistors) and related devices. The gas sensitivity of MISFET’s was first reported by Lundström et al. in 1975. Today a lot of work is being done in this field. LÄS MER
