  3. 12. Synthesis and Characterization of 2D Nanocrystals and Thin Films of Transition Metal Carbides (MXenes)

    Författare :Joseph Halim; Michael Barsoum; Lars Hultman; Yury Gogotsi; Per Eklund; Johanna Rosén; Jun Lu; Martin Magnuson; Ulf Jansson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Two dimensional (2D) materials have received growing interest because of their unique properties compared to their bulk counterparts. Graphene is the archetype 2D solid, but other materials beyond graphene, such as MoS2 and BN have become potential candidates for several applications. LÄS MER

  4. 13. Light emitting devices based on silicon nanostructures

    Författare :Nenad Lalic; KTH; []
    Nyckelord :;

    Sammanfattning : Although silicon is the dominant semiconductor today, lightemitting devices are currently based on compound semiconductorsdue to their direct band-gap, which promotes fast radiativerecombination. However, in nanometer-size silicon structures,carrier confinement enhances the radiative recombination,while, at the same time, suppresses diffusion to non-radiativerecombination centra, resulting in a significant increase inlight emission efficiency.

  5. 14. Development of macropore arrays in silicon and related technologies for X-ray imaging applications

    Författare :Xavier Badel; KTH; []
    Nyckelord :;

    Sammanfattning : Digital devices have started to replace photographic film inX-ray imaging applications. As compared to photographic films,these devices are more convenient to obtain images and tohandle, treat and store these images. LÄS MER
