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

    Author : Michael Gurnett; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : 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. READ MORE

  4. 7. Cathodic Arc Synthesis of Ti-Si-C-N Thin Films : Plasma Analysis and Microstructure Formation

    Author : Anders Eriksson; Johanna Rosén; Lars Hultman; Arutiun Ehiasarian; Linköpings universitet; []
    Keywords : ;

    Abstract : This Thesis explores the arc deposition process and films of Ti-Si-C-N, inspired by the two ternary systems Ti-Si-N and Ti-C-N, both successfully applied as corrosion and wear resistant films. The correlation between cathode, plasma, and film properties are studied for a comprehensive view on film formation. READ MORE

  5. 8. Structure and Electronic Properties of Phthalocyanine Films on Metal and Semiconductor Substrates

    Author : Ieva Bidermane; Carla Puglia; Nadine Witkowski; Nils Mårtensson; Luca Giovanelli; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phthalocyanines; silicon 100 ; Au 111 ; photoelectron spectroscopy; scanning tunneling microscopy; surface science; organic molecules on surface;

    Abstract : The current thesis presents fundamental studies of phthalocyanines (Pcs), a group of organic macro-cycle molecules. The use of phthalocyanine molecular films in devices with a variety of possible technological applications has been the reason of the many studies dedicated to such molecules during the last decades.

  7. 10. Interaction of Ni with SiGe for electrical contacts in CMOS technology

    Author : Johan Seger; Shi-Li Zhang; Christian Lavoie; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; MOSFET; NiSi; SiGe; phase formation; morphological stability; Fysik; Physics; Fysik;

    Abstract : This thesis investigates the reactive formation of Ni mono-gernanosilicide, NiSi1-uGeu, for contact metallization of future CMOS devices where Si1-xGex can be present in the gate, source and drain of a MOSFET. Although the investigation has been pursued with a strong focus on materials aspects, issues related to process integration in MOSFETs both on conventional bulk Si and ultra-thin body SOI have been taken into consideration.
