1. 21. Applications of Si1-xGex alloys for Ge devices and monolithic 3D integration

   Författare :Konstantinos Garidis; Per-Erik Hellström; Mikael Östling; Sten Vollebregt; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon; germanium; epitaxy; selective; pn junction; germanium on insulator; GOI; Ge PFET; bonding; monolithic; sequential; three dimensional; 3D; low temperature; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : As the semiconductor industry moves beyond the 10 nm node, power consumption constraints and reduction of the negative impact of parasitic elements become important. Silicon germanium (Si1−xGex) alloys have been used to amplify the performance of Si based devices and integrated circuits (ICs) for decades. LÄS MER

3. 22. Three-dimensional mapping of fine structure in the solar atmosphere

   Författare :Vasco M. J. Henriques; Dan Kiselman; Göran Scharmer; Hector Socas-Navarro; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sun; sunspots; Swedish 1-meter Solar Telescope; active regions; image processing; sunspot penumbra; Astronomy; astronomi;

   Sammanfattning : The effects on image formation through a tilted interference filter in a converging beam are investigated and an adequate compensation procedure is established. A method that compensates for small-scale seeing distortions is also developed with the aim of co-aligning non-simultaneous solar images from different passbands. LÄS MER

4. 23. Synthesis and characterization of two- and three-dimensional nanolaminated carbides

   Författare :Quanzheng Tao; Johanna Rosén; Per O A Persson; Amit Keren; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis is focused towards the synthesis and characterization of novel nanolaminated materials in primarily bulk (powder) form. Of particular interest is magnetic materials, or laminates that can be used as precursor for two-dimensional (2D) materials. LÄS MER

5. 24. Long bone growth and evolution revealed by three-dimensional imaging

   Författare :Jordi Estefa; Sophie Sanchez; Per Ahlberg; Holly Woodward; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 3D histology; hematopoiesis; humerus; tetrapods; Biologi; Biology;

   Sammanfattning : Propagation phase-contrast synchrotron radiation microtomography is a non-destructive method used for studying histology in three dimensions (3D). Using it, the 3D organization of the diaphyseal cortical vascularization in the humerus of two seymouriamorphs was analyzed in this thesis. LÄS MER

7. 25. Three dimensional data analysis for the separation and sizing of laboratory rock piles

   Författare :Matthew Thurley; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

   Sammanfattning : The size distribution of piles of blasted and crushed rock in mining is so closely related to the economics of the mine that it must be measured quickly and accurately. This thesis develops a mathematical and 3D imaging solution for determining the size distribution of laboratory rock piles based on surface measurements of the pile... LÄS MER
