  1. 16. 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)].

  3. 17. Theoretical Studies of Diamond for Electronic Applications

    Författare :Shuainan Zhao; Karin Larsson; Mats Boman; Gueorgui Gueorguiev; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diamond; Surface functionalization; Electronic structure; graphene; dopant; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Sammanfattning : Diamond has since many years been applied in electronic fields due to its extraordinary properties. Substitutional dopants and surface functionalization have also been introduced in order to improve the electrochemical properties. LÄS MER

  4. 18. 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.

    Författare :Tobias Törndahl; Jan-Otto Carlsson; Karin Larsson; Mikael Ottosson; Lauri Niinistö; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Atomic Layer Deposition; ALD; copper; copper I oxide; copper I nitride; deposition pathway; CuCl; Cu hfac 2; oxide substrates; epitaxy; DFT; ab-initio; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : Thin films play an important role in science and technology today. By combining different materials, properties for specific applications can be optimised. LÄS MER

  7. 20. Theoretical Investigations of Boron Related Materials Using DFT

    Författare :Igor Arvidsson; Karin Larsson; Jan-Otto Carlsson; Robert Jones; Uppsala universitet; []
    Nyckelord :Inorganic chemistry; boron nitride; density functional theory; chemical vapour deposition; atomic layer deposition; surface reactivity; adsorption; abstraction; computational chemistry; Oorganisk kemi;

    Sammanfattning : In the history of Chemistry, materials chemists have developed their ideas mainly by doing experiments in laboratories. The underlying motivation for this laboratory work has generally been pure curiosity or the ambition to find a solution to a specific problem. LÄS MER
