    Abstract : With the retreating sources of carbon based fuels, thermoelectric materials can play an important role in the future of environmentally friendly power generators. Sb based framework have in some cases shown some promising properties as thermoelectric materials. The physical properties may be modified with doping or incorporation of new elements. READ MORE

  3. 3. From understanding to realizing novel III-Sb materials via nanowires

    University dissertation from Solid State Physics, Lund University

    Author : Luna Namazi; [2018-02-27]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fysicumarkivet A:2018:Namazi;

    Abstract : Due to their unique physical and material properties, III-Sb nanowires are considered good candidates for future devices, and test beds for understanding fundamental physics. Synthesizing these nanowires however is associated with certain challenging aspects, which are generally not present for other III-V nanowires, demanding the need for in depth investigations.

  4. 4. Low Temperature Structural and Property investigations in the Zn-Sb System

    University dissertation from Stockholm : Institutionen för fysikalisk kemi, oorganisk kemi och strukturkemi

    Author : Johanna Nylén; Sven Lidin; Jeff Snyder; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermoelectrics; Zinc antimmonides; Metal doped semiconductors; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; oorganisk kemi; Inorganic Chemistry;

    Abstract : Thermoelectric Zn4Sb3 has a randomly disordered crystal structure at room temperature and undergoes a reversible sequence of phase transitions, β-α-α’/α, at low temperatures. During the transformations interstitial Zn atoms and Zn vacancies present in the β-phase become increasingly ordered. READ MORE
