  1. 1. Nanofabrication of Diffractive Soft X-ray Optics

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Magnus Lindblom; KTH.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanofabrication; Zone plate; x-ray; diffractive x-ray optics; x-ray microscopy; NATURAL SCIENCES Physics Other physics Optics; NATURVETENSKAP Fysik Övrig fysik Optik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : This thesis summarizes the present status of the nanofabrication of diffractive optics, i.e. zone plates, and test objects for soft x-ray microscopy at KTH. The emphasis is on new and improved fabrication processes for nickel and germanium zone plates. READ MORE

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

    University dissertation from Stockholm, Sweden : KTH Royal Institute of Technology

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

    Abstract : 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.

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

    University dissertation from Division of Solid State Physics, Lund University, P.O. Box 118, S-221 00 Lund, Sweden

    Author : Jonas Tegenfeldt; Lund University.; Lunds universitet.; [1997]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University dissertation from Stockholm : KTH Royal Institute of Technology

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

    Abstract : 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. READ MORE

  5. 5. Nanostructures of Graphite and Amorphous Carbon - Fabrication and Properties

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Hans Fredriksson; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; optical resonance; Raman-spectrum; carbon; optical spectrum; HOPG; GC amorphous carbon; oxidation; Nanofabrication;

    Abstract : Nanoscience is a well-established research area, which concerns properties and fabrication of objects with typical dimensions on the 1-100 nanometer length scale. A central issue has been the development of techniques for fabrication and characterization of nanometer sized objects, which have contributed considerably to progress in both practical applications and fundamental research.
