2. 1. Characterization of Process-related Defects in Silicon Carbide by Electron Microscopy

   Author : Per O. Å. Persson; Pirouz Pirouz; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Silicon carbide (SiC) is a semiconducting material, which provides advantages compared to other available semiconducting materials. Attractive properties of SiC are the wide bandgap (2.2-3.3 eV), high electric breakdown field (3x106 Vcm-1), high thermal conductivity (5 Wcm-1 K-1) and the chemical stabi!ity. READ MORE

4. 2. Synthesis and characterization of magnetic nanolaminated carbides

   Author : Andrejs Petruhins; Johanna Rosén; Per O. Å. Persson; Niklas K. Hellgren; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : MAX phases are a group of nanolaminated ternary carbides and nitrides, with a composition expressed by the general formula Mn+1AXn (? = 1 − 3), where M is a transition metal, A is an A-group element, and X is carbon and/or nitrogen. MAX phases have attracted interest due to their unique combination of metallic and ceramic properties, related to their inherently laminated structure of a transition metal carbide (Mn+1Xn) layer interleaved by an A-group metal layer.

5. 3. Scaling sufficiency : Towards less material consumption

   Author : Ola Persson; Karin Bradley; Mikael Klintman; Kersty Hobson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Urban and Regional Studies; Urbana och regionala studier;

   Abstract : Various researchers have pointed out that avoiding further catastrophicconsequences related to the deteriorating ecological state of the planet,brought about by unsustainable production and consumption patterns,requires not only technological innovation and efficiency in productionprocesses, but also absolute reductions in energy and material use (i.e. READ MORE
