  1. 16. CVD Growth of Silicon Carbide for High Frequency Applications

    Författare :Urban Forsberg; Erik Janzén; Anne Henry; Christian Brylinski; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material physics with surface physics; Materialfysik med ytfysik;

    Sammanfattning : Silicon Carbide (SiC) is an important wide band gap semiconductor with outstanding electronic properties. With figures of merit far better than silicon, SiC is believed to replace and outcompete silicon in many applications using high frequencies, high voltage and high temperatures. LÄS MER

  3. 17. Application of X-ray Computed Tomography for Assessment of Additively Manufactured Products

    Författare :Amir Reza Zekavat; Lars Pejryd; Leonardo De Chiffre; Örebro universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; X-ray computed tomography; Surface roughness;

    Sammanfattning : Additive Manufacturing (AM) is a novel method for fabricating parts from three-dimensional model data, usually by joining materials in layer upon layer fashion. The freedom of design in this method has resulted in new possibilities for fabrication of parts with complex geometries. LÄS MER

  4. 18. Deformation and Fracture Behavior of Transparent Wood-Polymer Biocomposites

    Författare :Erik Jungstedt; Lars Berglund; Sören Östlund; Bent Sørensen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocomposites; fracture mechanics; strain field measurement; cohesive zone modeling; mechanical properties; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : Transparent wood-polymer biocomposites (TWPBs) are interesting wood-based materials with a unique combination of optical transmittance and mechanical properties. The wood substrate is delignified (removal of lignin) while the wood microstructure is preserved. LÄS MER

  5. 19. Silicon nanowires, nanopillars and quantum dots : Fabrication and characterization

    Författare :Robert Juhasz; Jan Linnros; Philippe M. Fauchet; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silicon nanowires; silicon nanopillars; silicon quantum dots; size-reduction; thermal oxidation; electrochemical etching of silicon; photoluminescence; Semiconductor physics; Halvledarfysik;

    Sammanfattning : Semiconductor nanotechnology is today a very well studied subject, and demonstrations of possible applications and concepts are abundant. However, well-controlled mass-fabrication on the nanoscale is still a great challenge, and the lack of nanofabrication methods that provide the combination of required fabrication precision and high throughput, limits the large-scale use of nanodevices.
