    Abstract : This work focuses on the design, synthesis, characterization, and application projections of low-coordinated heavy pnictogen-containing (described by the generic letter E, hence E=C) phosphaalkenes (P=C) and arsaalkenes (As=C), with emphasis on the E=C group motifs. The work aims to understand their functional and modular character, reactivity, and potential applications by stabilizing, isolating, and characterizing these species in low-coordination environments.

    Abstract : Hydrogen peroxide (H2O2) is an important oxidant, used in various fields of industry, such as paper manufacturing, production of polymers, detergents, and cosmetics. Considering that the molecule degrades only to H2O and O2, it is regarded as a green chemical. READ MORE

  5. 3. Electrical properties of polycrystalline silicon

    Author : Matts Rydberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Elektronik; Electronics;

    Abstract : Polysilicon is used, among other materials, in today's integrated circuits. In this thesis, the structural and electrical properties' of polysilicon thin film resistors have been studied. The aim has been to improve the long-term stability and increase the knowledge concerning grain-boundary related phenomena. READ MORE

  6. 4. Hydrogen diffusion and ion implantation in silicon carbide

    Author : Martin Janson; KTH; []
    Keywords : heat abd tgernidtbanucs; electronics and electrical; materials science;

    Abstract : Secondary ion mass spectrometry (SIMS) has been employed tostudy the spatial distributions resulting from mass transportby diffusion and ion implantation in single crystal siliconcarbide (SiC). By a systematic analysis of this data,fundamental processes that govern these phenomena have beenderived. READ MORE
