3. 2. Solution-Processable Conductive Graphene-Based Materials for Flexible Electronics

   Författare :Jie Zhao; Zhi-Bin Zhang; Shi-Li Zhang; Matti Mäntysalo; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; Graphene oxide; Silver; Copper; Composite; Conductive inks; Flexible electronics; Printed electronics; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Sammanfattning : This thesis work explores electrical conductors based on few-layer graphene flakes as an enabler for low-cost, mechanically flexible, and high-conductivity conductors in large area flexible and printed electronic devices. The flakes are deposited from aqueous solutions and processed at low temperature. LÄS MER

4. 3. Oxidation and Corrosion of New MCrAlX Coatings : Modelling and Experiments

   Författare :Kang Yuan; Ru Lin Peng; Xin-Hai Li; Sten Johansson; Yan-Dong Wang; Robert Vaβen; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : MCrAlY coatings (“M” for Ni and/or Co) are widely used for the protection of superalloy components operated at high temperatures such as in the hot sections of gas turbines. The exposure to high temperature can cause coating degradation due to oxidation or hot corrosion at the coating surface. LÄS MER

5. 4. Design of efficient high-speed on-chip global interconnects

   Författare :Peter Caputa; Li-Rong Zheng; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The development of integrated circuits is continuously moving towards a System-on­ Chip realization where global interconnects, connecting circuit blocks separated by a long distance, have been considered a showstopper for process scaling due to their RC-delays. Our knowledge today is that high-speed interconnects must be described by models which include not only R and C, but also inductance and skin effect. LÄS MER

7. 5. Photoemission Studies of the M/Si(111)-3x1 Reconstructions for M=Li, Na, K, and Ag

   Författare :Michael Gurnett; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Sammanfattning : The work reported here relates to a class of reconstructions on the Si(111) surface with 3?1 or 6?1 periodicity that are believed to be similar for Ag, Mg and the alkali metals (Li, K, and Na). The electronic structure of this reconstruction was studied by means of angle-resolved photoelectron spectroscopy of the valence bands of the Ag/Si(111)-3?1/6?1 reconstruction. LÄS MER
