  4. 2. Photon Upconversion in Heavily Doped Semiconductors

    Author : Kilian Mergenthaler; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V semiconductor materials; nanowires; photoluminescence; Photon upconversion; semiconductors; doping; Fysicumarkivet A:2016:Mergenthaler;

    Abstract : In this thesis the luminescence properties of highly doped semiconductors are studied with focus on degenerately n-doped InP. It is demonstrated how photoluminescence measurements on degenerately doped semiconductors allow an estimation of the doping concentration without need for electrical contacts. READ MORE

  5. 3. New C-C coupling Reactions Enabled by Main-group Organometallics

    Author : Kilian Colas; Abraham Mendoza; David Procter; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; C-C coupling; organometallics; aluminum; magnesium; Grignard; turbo-Hauser-bases; piperazines; sulfur; ketones; organisk kemi; Organic Chemistry;

    Abstract : The carbon-carbon bond has always been at the very core of chemical research. Strategies for the creation of C−C bonds are one of the keys to the construction game that organic chemists play with the building blocks provided by Nature, with the ultimate goal of producing useful molecular structures that will serve society as medicines, materials, imaging tools, catalysts, and ligands (to mention but a few).

  6. 4. On Long Proofs of Simple Truths

    Author : Kilian Risse; Per Austrin; Johan Håstad; Jakob Nordström; Benjamin Rossman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational Complexity; Lower Bounds; Proof Complexity; Datalogi; Computer Science;

    Abstract : Propositional proof complexity is the study of certificates of infeasibility. In this thesis we consider several proof systems with limited deductive ability and unconditionally show that they require long refutations of the feasibility of certain Boolean formulas. READ MORE

  7. 5. Metal-Free O- and C-Arylation with Diaryliodonium Salts

    Author : Erik Lindstedt; Berit Olofsson; Kilian Muñiz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hypervalent Iodine; Alkyl Aryl Ethers; Nitro Compounds; Alcohols; Diaryliodonium Salts; organisk kemi; Organic Chemistry;

    Abstract : This thesis concerns the development of metal-free applications using diaryliodonium salts. The first project describes an arylation protocol of allylic and benzylic alcohols in aqueous media. The method proceeds under mild conditions and the ether products were obtained in moderate to good yields. READ MORE
