1. 16. The influence of growth temperature on CVD grown graphene on SiC

   Master-uppsats, Linköpings universitet/Halvledarmaterial; Linköpings universitet/Tekniska fakulteten

   Författare :Andréa Nicollet; [2015]
   Nyckelord :CVD; graphene; SiC; Raman spectroscopy; AFM; reflectance mapping;

   Sammanfattning : Graphene is one of the most popular material due to its promising properties, for instance electronics applications. Graphene films were grown on silicon carbide (SiC) substrate using chemical vapor deposition (CVD). Influence of the deposition temperature on the morphology of the films was investigated. LÄS MER

   Nyckelord :Silicon carbide; Cubic silicon carbide; 3C-SiC; Bulk; Sublimation epitaxy; Seeded sublimation growth;

   Sammanfattning : The growth of bulk cubic silicon carbide has for a long time seemed to be something for the future. However, in this thesis the initial steps towards bulk cubic silicon carbide have been taken. LÄS MER

4. 18. Optical properties of free-standing cubic silicon carbide

   Master-uppsats, Linköpings universitet/Halvledarmaterial; Linköpings universitet/Tekniska fakulteten

   Författare :Mattias Jansson; [2015]
   Nyckelord :semiconductor; silicon carbide; SiC; photovoltaic; water splitting; sublimation;

   Sammanfattning : The properties of free-standing cubic silicon carbide for optoelectronic applications are explored in this work. The main focus of the work is on boron doped cubic silicon carbide, which is proposed as a highly useful material in several optoelectronic applications. LÄS MER

5. 19. "Propuesta indecente" : Tratamiento de la mujer en textos de bachata

   Kandidat-uppsats, Umeå universitet/Institutionen för språkstudier

   Författare :Ondina Plasencia; [2015]
   Nyckelord :Género; análisis de canciones; mujer; República Dominicana; igualdad; patriarcado; bachata;

   Sammanfattning : Resumen   Esta investigación trata del análisis con perspectiva de género de cinco canciones de bachata. Quiero saber cuál es el tratamiento a la mujer en los textos de este este estilo musical. La sociedad dominicana es muy patriarcal y los “amores patriarcales” se reflejan en muchas áreas de la sociedad especialmente en la música. LÄS MER

7. 20. Characterization of epitaxial graphene grown on silicon carbide

   Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

   Författare :Anton Jansson; [2014]
   Nyckelord :Graphene; epitaxial graphene; silicon carbide; SiC; 4H-SiC; 6H-SiC; sublimation; graphene manufacturing; AFM; atomic force microscopy; tapping mode; surface study; stepheight; charactarization;

   Sammanfattning : In this thesis work several manufacturing methods for graphene is discussed followed by an indepth study of graphene grown by a high temperature sublimation method (sublimation of siliconcarbide). The graphene surfaces studied have been grown by Graphensic AB, both graphenegrown on the Si-face and the C-face of the silicon carbide were studied. LÄS MER
