    Författare :Denis Chouvaev; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis concerns development of the Normal metal hot-electron microbolometer (NHEB). The NHEB is an antenna-coupled direct detector of sub-millimeter wave electromagnetic radiation. LÄS MER

  5. 4. Heterogeneous material integration for MEMS

    Författare :Fredrik Forsberg; Frank Niklaus; Lina Sarro; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis describes heterogeneous integration methods for the fabrication of microelectromechanical systems (MEMS). Most MEMS devices reuse the fabrication techniques that are found in the microelectronics integrated circuit industry. This limits the selection of materials and processes that are feasible for the realization of MEMS devices. LÄS MER
