  3. 3. High-Aspect Ratio Nanofabrication for Hard X-Ray Zone Plates

    Detta är en avhandling från Stockholm, Sweden : KTH Royal Institute of Technology

    Författare :Karolis Parfeniukas; KTH.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanofabrication; x-ray optics; zone plate; tungsten; silicon; reactive ion etching; metal-assisted chemical etching; Ronchi test; Physics; Fysik;

    Sammanfattning : Hard x-ray nanoimaging enables structural investigations of new materials for many applications. For high-resolution experiments, zone plate x-ray optics are commonly chosen.Two methods of zone plate nanofabrication are presented in this thesis.Zone plates are circular diffraction gratings with radially decreasing grating period.

  4. 4. Nanofabrication and Characterization for Applications in Biochemistry and Molecular Electronics

    Detta är en avhandling från Division of Solid State Physics, Lund University, P.O. Box 118, S-221 00 Lund, Sweden

    Författare :Jonas Tegenfeldt; Lund University.; Lunds universitet.; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanofabrication; chemical functionalization; silanization; scanning force microscopy; AFM; lateral forces; image processing; admittance spectroscopy; Physics; biosensors; Biokemi; Fysicumarkivet A:1997:Tegenfeldt; Metabolism; Fysik; Biochemistry; localized etching;

    Sammanfattning : As man-made structures are made increasingly smaller it becomes possible to conduct measurements on single cells, molecules and eventually atoms. In this thesis prerequisites for making this possible are discussed. The underlying thought is that the structures should be used in biological and organic based applications. LÄS MER

  5. 5. Nanofabrication of Zone Plates for Hard X-Ray Free-Electron Lasers

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Fredrik Uhlén; KTH.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray optics; Zone plates; Nanofabrication; X-ray free-electron lasers; Physics; Fysik;

    Sammanfattning : This Thesis describes the development of hard X-ray zone plates intended for focusing radiation at X-ray free-electron lasers (XFELs). XFELs provide unprecedented brightness and zone plates which are put in the intense X-ray beam are at risk of being damaged. LÄS MER
