1. 11. Covalent functionalization of carbon nanomaterials for bioelectrochemical applications

   Författare :Naoual Allali; Alexander Soldatov; Manuel Dossot; Victor Mamane; Silvia Giordani; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

   Sammanfattning : Carbon nanotubes (CTNs) are renowned for their exceptional electronic and mechanical properties. Their structure can be considered as rolling up a graphene sheet along a specific crystallographic direction, leading to a 1D confinement of the electronic wavefunction of the delocalized electrons along the perimeter of the cylindrical structure thus obtained.

   Sammanfattning : In the past decade the interest in molecular electronic devices has escalated. The synthesis of molecular crystals has improved, providing single crystals or thin films with mobility comparable with or even higher than amorphous silicon. Their mechanical flexibility admits new types of applications and usage of electronic devices. LÄS MER

4. 13. Physical Properties and Structural stability of carbon nanotubes under extreme conditions

   Författare :Maxime Noël; Roberts Joffe; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics; Physics; Fysik;

   Sammanfattning : Carbon nanotubes (CNTs) have attracted an immense attention of the research community since reporting on this system by S. Ijima in 1991. A "single-walled" CNT (SWCNT) can be considered as a rolled-up single-layer graphene - a one atom-thick layer of carbon atoms arranged in a hexagonal lattice. LÄS MER
