2. 1. Synthesis and characterization of Mo-based nanolaminates

   Author : Rahele Meshkian; Johanna Rosén; Árni Sigurður Ingason; Hans Högberg; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Mn+1AXn (MAX) phases are nanolaminated compounds based on a transition metal (M), a group A element (A), and carbon or/and nitrogen (X), which exhibit a unique combination of ceramic and metallic properties. Mo-based MAX phases are among the least studied, despite indication of superconducting properties and high potential for fabrication of the grapheneanalogous 2D counterpart, Mo2C MXene. READ MORE

4. 2. Synthesis and characterization of Ga-containing MAX phase thin films

   Author : Andrejs Petruhins; Johanna Rosén; Per O A Persson; Erik Lewin; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The study of magnetic Mn+1AXn (MAX) phases (n = 1 − 3, M – a transition metal, A – an A group element, X – C or N) is a recently established research area, fuelled by theoretical predictions and first confirmed experimentally through alloying of Mn into the well-known Cr2AlC and Cr2GeC. Theoretical phase stability investigations suggested a new magnetic MAX phase, Mn2GaC, containing Ga which is liquid close to room temperature. READ MORE

5. 3. Synthesis and characterization of magnetic nanolaminated carbides

   Author : Andrejs Petruhins; Johanna Rosén; Per O. Å. Persson; Niklas K. Hellgren; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : MAX phases are a group of nanolaminated ternary carbides and nitrides, with a composition expressed by the general formula Mn+1AXn (? = 1 − 3), where M is a transition metal, A is an A-group element, and X is carbon and/or nitrogen. MAX phases have attracted interest due to their unique combination of metallic and ceramic properties, related to their inherently laminated structure of a transition metal carbide (Mn+1Xn) layer interleaved by an A-group metal layer.

6. 4. Synthesis and Characterization of Ternary Carbide Thin Films

   Author : Ola Wilhelmsson; Ulf Jansson; Michael Stueber; Uppsala universitet; []
   Keywords : Chemistry; Thin film; dc magnetron sputtering; tribology; carbide; PVD; MAX-phase; DFT; solid solution; Kemi;

   Abstract : This thesis reports on synthesis, microstructure and properties of binary and ternary carbide thin films deposited by dc magnetron sputtering. These materials are interesting since they exhibit a wide range of useful properties, such as high hardness, resistance to wear and oxidation, and high electrical conductivity. READ MORE

7. 5. Materials Design from First Principles : stability and magnetism of nanolaminates

   Author : Martin Dahlqvist; Johanna Rosén; Nicola Spaldin; Linköpings universitet; []
   Keywords : ;

   Abstract : In this thesis, first-principles calculations within density functional theory are presented, with a principal goal to investigate the phase stability of so called Mn+1AXn (MAX) phases. MAX phases are a group of nanolaminated materials comprised of a transition metal (M), a group 12-16 element (A), and carbon or nitrogen (X). READ MORE
