  2. 6. Elastic Stability and Piezoelectric Power Generation Using ZnO Nanostructures

    Author : Riaz Mohammad; Magnus Willander; Omer Nour; Shunri Oda; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Nanotechnology combines the effort between science and engineering using the approaches of either top-to-bottom or bottom-to-top techniques. A hybrid approach of the above techniques is also used for the fabrication of nanodevices. READ MORE

  4. 7. Design and characterization of nanoparticles and their assemblies : Transmission electron microscopy investigations from atomic to mesoscopic length scales

    Author : Arnaud Mayence; Lennart Bergström; Liberato Manna; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; electron microscopy; Materials Chemistry; materialkemi;

    Abstract : Transmission electron microscopy (TEM) is a powerful and versatile tool for investigating nanomaterials. In this thesis, various transmission electron microscopy techniques are used to study the chemical and structural features of different types of inorganic nanoparticles of well-defined morphologies as well as their assemblies.

  5. 8. Heterojunctions between zinc oxide nanostructures and organic semiconductor

    Author : Amal Hansson (f.d. Wadeasa); Xavier Crispin; Dominique Vuillaume; Linköpings universitet; []
    Keywords : ZnO nanostructures; Organic semiconductors; LEDs; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Lighting is a big business, lighting consumes considerable amount of the electricity. These facts motivate for the search of new illumination technologies that are efficient. Semiconductor light emitting diodes (LEDs) have huge potential to replace the traditional primary incandescent lighting sources. READ MORE

  6. 9. Fabrication and Photoelectrochemical Applications of II-VI Semiconductor Nanomaterials

    Author : Abhilash Sugunan; Muhammet Toprak; Mamoun Muhammed; Gerrit Boschloo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ZnO; nanowire arrays; photocatalysis; CdTe; CdSe; CdS; nanotetrapods; nanotetrahedrons; photoconduction; nano-gap electrodes; Type-II QDs; P3HT nanofibers; microwave synthesis.;

    Abstract : In this work we investigated fabrication of semiconductor nanomaterials and evaluated their potential for photo-chemical and photovoltaic applications. We investigated different II-VI semiconductor nanomaterial systems; (i) ZnO oriented nanowire arrays non-epitaxially grown from a substrate; and (ii) colloidal CdE (E=Te,Se,S) quantum structures synthesized by solution-based thermal decomposition of organo-metallic precursors.
