1. 6. Chemical Vapour Deposition of sp2 Hybridised Boron Nitride

   Författare :Mikhail Chubarov; Anne Henry; Henrik Pedersen; Hans Högberg; Robert F. Davis; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The aim of this work was to develop a chemical vapour deposition process and understand the growth of sp2 hybridised Boron Nitride (sp2-BN). Thus, the growth on different substrates together with the variation of growth parameters was investigated in details and is presented in the papers included in this thesis. LÄS MER

4. 8. The Effect of Boron in Metal Borides and BN – A Theoretical Approach

   Författare :Anna Pallas; Karin Larsson; R. (Bob) Jones; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic Chemistry; Oorganisk kemi;

   Sammanfattning : Boron, B, has many interesting electronic and structural properties, which makes it an ideal material for technical and industrial needs. The different binary materials that have been in focus in the present thesis, do all include B; metal diborides (MB2), cubic boron nitride (c-BN) forming an interface with diamond, and various phases of BN [cubic (c-BN), hexagonal (h-BN), wurtzitic (w-BN), and rhombohedral (r-BN)].

5. 9. Exploration of Graphene-like 2D Materials for Energy Management and Interface Enhancement Applications

   Författare :Ya Liu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Industrial Application; Graphene-like 2D materials; Interface Enhancement; Energy Management;

   Sammanfattning : Ever since the discovery of graphene in 2004, graphene-like 2D materials and their derivatives have attracted extensive investigations because of their exceptional physical and chemical properties. At present, the study of graphene-like 2D materials is at a stage where most of their outstanding physical and chemical properties have been discovered, but the technology for incorporating them into practical commercial products is rarely revealed.

7. 10. Studies on Growth of SiC and BN : from Theory and Experiments

   Författare :Jenny Olander; Karin Larsson; Jan-Otto Carlsson; Alison Mainwood; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Growth; quantum chemistry; DFT; ALD; laser-activation; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : Smaller cellular telephones and more energy-efficient windows are just two examples of technological advances which call for new materials. Materials chemists seek to develop new materials, both out of pure curiosity to see which combination of elements and structures can be obtained and in efforts to produce materials, with specific properties.
