  2. 11. Wafer Bonding for Spaceflight Applications : Processing and Characterisation

    Author : Kerstin Jonsson; Maaike Visser-Taklo; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; wafer bonding; oxygen plasma; wet chemical; anodic bonding; gamma irradiation; proton irradiation; temperature cycling; vibration; shock; Weibull; adhesion quantification; double cantilever beam; tensile; chevron; blister; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : Bonding techniques intended for assembling space microsystems are studied in this work. One of the largest problems in bonding pre-processed semiconductor wafers are the severe process restrictions imposed by material compatibility issues. READ MORE

  4. 12. Superconducting kinetic inductance devices for nanoscale force sensing

    Author : August K. Roos; David B. Haviland; Hélène le Sueur; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optomechanics; force sensing; atomic force microscopy; kinetic inductance; superconductivity; strain; meandering nanowires; optomekanik; kraftavkänning; atomkraftsmikroskopi; kinetisk induktans; supraledning; töjning; slingrande nanotrådar; Material and Nano Physics; Material- och nanofysik;

    Abstract : In this thesis, we present a force sensor for atomic force microscopy based on cavity optomechanical principles. We explain the function, design, fabrication and characterisation of the force sensor. The mechanical part of the force sensor consists of a cantilever with a very fine tip. READ MORE

  5. 13. Imaging materials with intermodulation : Studies in multifrequency atomic force microscopy

    Author : Daniel Forchheimer; David Haviland; Arvind Raman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; atomic force microscopy; nonlinear dynamics; frequency mixing; force reconstruction; Fysik; Physics;

    Abstract : The Atomic Force Microscope (AFM) is a tool for imaging surfaces at the microand nano meter scale. The microscope senses the force acting between a surfaceand a tip positioned at the end of a micro-cantilever, forming an image of the surface topography. READ MORE

  6. 14. A study of hydroelastic fluid-structure interaction with application to immersed cantilevers

    Author : Johan Lorentzon; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Partitioned Fluid-Structure; Blocked Gauss-Seidel; Jacobian-free Newton-Krylov methods; Incompressible fluid; Finite Strain; Total Lagrangian; Arbitrary Lagrange Euler method; Vector acceleration;

    Abstract : This study presents an approach for partitioned fluid-structure interaction (FSI) applied to large structural deformations, where an incompressible turbulent solver is combined with a structural solver. The implementation is based upon two different open-source libraries by using MPI as a parallel communication protocol, the packages deal. READ MORE

  7. 15. Nanoimprint Lithography Based Nanoelectromechanical Device Fabrication

    Author : Gang Luo; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis presents studies concerning the development of nanoimprint lithography technology, nanoimprint lithography-based nanofabrication, as well as the production of NEMS devices and their characterization. It can be divided into the following parts: The first part introduces different NIL stamp fabricating methods and processes. READ MORE
