2. 6. Computational Studies of Metal Clusters and Carbon Nanotubes

   Author : Anders Börjesson; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; carbon nanotube; metal clusters; nanotubesmetal junction; melting temperatures; nanotechnology; molecular dynamics; monte carlo; tight binding; atomistic simulations; Energi och material;

   Abstract : Carbon nanotubes constitute a promising candidate material in the realisation of nanoscaled electronics. This requires the ability for systematic production of carbon nanotubes with certain properties. This is called selective carbon nanotube growth. READ MORE

4. 7. Microstructure aspects of transition metal carbide thin films

   Author : Jun Lu; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; vapour deposition; transition metal carbide; nanocrystallinity; epitaxy; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

   Abstract : Transition metal carbides are important refractory materials used in many thin film applications. In this thesis, several transition metal carbides have been deposited using different chemical vapour deposition (CVD) and evaporation processes. In particular, the phase composition and microstructure of these carbide films have been studied. READ MORE

5. 8. Thermal laser-assisted chemical vapour deposition : aspects of kinetics and materials structures

6. 9. Surface Science Studies of Metal Oxides Formed by Chemical Vapour Deposition on Silicon

   Author : Patrik Karlsson; Anders Sandell; Håkan Rensmo; Marcus Bäumer; Uppsala universitet; []
   Keywords : Physics; chemical vapour deposition; high-k; metal oxides; silicon; dye-solid interface; metal organic; electron spectroscopy; scanning tunnelling microscopy; Fysik;

   Abstract : For an electronic device well-designed interfaces are critical for the performance. Studies of interfaces down to an atomic level are thus highly motivated both from a fundamental and technological point of view. READ MORE

7. 10. High dynamic stiffness nano-structured composites for vibration control : A Study of applications in joint interfaces and machining systems

   Author : Qilin Fu; Cornel-Mihai Nicolescu; Per Nylén; KTH; []

   Abstract : Vibration control requires high dynamic stiffness in mechanical structures for a reliable performance under extreme conditions. Dynamic stiffness composes the parameters of stiffness (K) and damping (η) that are usually in a trade-off relationship. This thesis study aims to break the trade-off relationship. READ MORE
