  2. 1. Vertical III-V Nanowire Tunnel Field-Effect Transistor

    Author : Elvedin Memisevic; Nanoelektronik; []
    Keywords : Transistor; TFET; Steep slope; Nanowire; III-V materials; HSQ; Vertical; InAs; GaSb; MOSFET;

    Abstract : In this thesis fabrication and optimization of vertical III-V Tunneling Field-Effect transistors was explored. Usage of vertical nanowires, allows for combination of materials with large lattice mismatch in the same nanowire structure. READ MORE

  4. 2. Femtosecond Laser Microfabrication of Glasses and 2D Materials for Photonics and Energy Storage

    Author : Po-Han Huang; Frank Niklaus; Göran Stemme; Kristinn Gylfason; Yves Bellouard; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Femtosecond laser; 3D printing; self-organized nanogratings; micromachining; silica glass; silicon-rich glass; hydrogen silsesquioxane; photonic microdevice; microsupercapacitor; 2D materials; direct ink writing; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Femtosecond laser-based fabrication technologies have seen rapid developments in the past decades, thanks to the capability of femtosecond lasers to induce localized multiphoton absorption in materials. Multiphoton absorption can result in various material modifications that can be leveraged for additive and subtractive manufacturing. READ MORE

  5. 3. High-Resolution Nanostructuring for Soft X-Ray Zone-Plate Optics

    Author : Julia Reinspach; Hans M. Hertz; Sasa Bajt; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; zone plates; x-ray optics; x-ray microscopy; high resolution; nanofabrication; electron beam lithography; reactive ion etching; tungsten; nickel; germanium;

    Abstract : Diffractive zone-plate lenses are widely used as optics in high-resolution x-ray microscopes. The achievable resolution in such microscopes is presently not limited by the x-ray wavelength but by limitations in zone-plate nanofabrication. READ MORE

  6. 4. Luminescent Silicon Nanocrystals: From Single Quantum Dot to Light-harvesting Devices

    Author : Jingjian Zhou; Ilya Sychugov; Jan Linnros; Peter Schall; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; silicon quantum dots; photoluminescence; quantum yield; internal quantum efficiency; luminescent solar concentrator; Optics and Photonics; Optik och fotonik;

    Abstract :       Silicon (Si) serves as the basic material of the system-on-a-chip industry and photovoltaic panels nowadays. This is mostly thanks to its high abundance in the earth’s crust, thereby low cost, virtually non-toxicity, and superior stability. READ MORE
