2. 6. Photon stimulated CVD of amorphous carbon thin films : By Mikael Lindstram

   Author : Mikael Lindstam; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; photolysis; thermal activation; CVD; amorphous carbon; modelling; kinetics; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

   Abstract : Amorphous carbon has attracted much interest for several decades now because of its complex crystal structure and microstructure. Depending on the carbon sp2/sp3 bonding ratio, these materials yield a broad spectrum of useful properties; which can be tailored for specific applications. READ MORE

4. 7. Aging and heat-sealing properties of films based on wheat gluten

   Author : Sung-Woo Cho; Mikael Hedenqvist; Minna Hakkarainen; Mikael Lindström; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheat gluten; aging; migration; opacity; heat sealability; shear strength; Polymer chemistry; Polymerkemi;

   Abstract : Recently the research interest of the possibility of using wheat gluten (WG) as packaging material has greatly increased due to its combination of high gas barrier, attractive mechanical, film-forming and renewable properties. The source is also readily available and inexpensive on a worldwide basis. READ MORE

5. 8. Design Optimization and Realization of 4H-SiC Bipolar Junction Transistors

   Author : Hossein Elahipanah; Mikael Östling; Carl-Mikael Zetterling; Anders Hallèn; Adolf Schöner; Tsunenobu Kimoto; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 4H-SiC; BJT; high-voltage and ultra-high-voltage; high-temperature; self-aligned Ni-silicide Ni-SALICIDE ; lift-off-free; wafer-scale; current gain; Darlington; Electrical Engineering; Elektro- och systemteknik; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : 4H-SiC-based bipolar junction transistors (BJTs) are attractive devices for high-voltage and high-temperature operations due to their high current capability, low specific on-resistance, and process simplicity. To extend the potential of SiC BJTs to power electronic industrial applications, it is essential to realize high-efficient devices with high-current and low-loss by a reliable and wafer-scale fabrication process.
