  2. 1. Adventures of III-V Semiconductor Surfaces

    Author : Sandra Benter; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; III-V; semiconductor surfaces; Bismuth; InAs; GaAs; droplets; STM; XPS; XPEEM; ARPES; Fysicumarkivet A:2023:Benter;

    Abstract : Tailoring the surface composition and morphology of materials to enable new electronic devices is important for a wide range of applications such as quantum computing or spintronics. A fundamental understanding of the changes induced in the surface during different process steps can help to establish new synthesis routes as well as devices. READ MORE

  4. 2. Modulations in Intermetallic Families of Compounds

    Author : Hanna Lind; Sven Lidin; Gervais Chapuis; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; intermetallic; incommensurate structure; single crystal X-ray diffraction; Inorganic chemistry; Oorganisk kemi;

    Abstract : This thesis is based on a study of five distinct intermetallic systems with the aim of expanding the general knowledge of aperiodically modulated crystal structures. Families of compounds that contain a variety of superstructures together with incommensurately modulated structures have been investigated mainly by means of single crystal X-ray diffraction and higher dimensional structure models.

  5. 3. Subvalent Cluster Compounds and Synthesis in Alternative Reaction Media

    Author : Josefin Åkerstedt; Lars Kloo; Mats Johnsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal cluster; Zintl ion; metal-organic sandwich complex; ionic liquid; X-ray diffraction; spectroscopy; crystal structure; Inorganic Chemistry;

    Abstract : With the aim of finding alternative reaction media for the synthesis of subvalent main group and transition metal cluster compounds, traditionally made through solid state reactions or in superacidic media, different alternative reaction media have been explored in this work. Room-temperature ionic liquids are amongst the more unconventional reaction media used. READ MORE

  6. 4. Tailored Reaction Media for the Synthesis of Subvalent Cluster Compounds

    Author : Josefin Åkerstedt; Lars Kloo; Sven Lidin; Ulf Gedde; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Inorganic Chemistry;

    Abstract : Different synthetic approaches and modifications to reaction media have been applied in order to find new routes to the synthesis of main-group clusters and transition metal compounds. The focus has been on the Group 15 element bismuth and the transition metal palladium. READ MORE

  7. 5. Studies on the Recovery of Secondary Antimony Compounds from Waste

    Author : Toni Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Morphology; Thermolysis; Leaching; Municipal Solid Waste; Zinc; Metal Oxide Varistor; Cementation; Fly Ash; Recycling; Antimony;

    Abstract : The global supply of antimony is dominated by one country which has led the European Union to classify antimony as a critical raw material. Other than the rare-earth elements antimony has the highest supply risk. Therefore, a feasibility study on the recycling of antimony and antimony compounds is of great importance. READ MORE
