  2. 1. Electrical Characterization of Integrated InAs Nano-Structures

    Author : Gvidas Astromskas; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DLTS; Fermi level pinning; epitaxial growth; threshold voltage; nanowire capacitance; overgrowth; Hall mobility; GaSb; InAs;

    Abstract : This thesis analyzes the electrical properties of InAs nano-structures, that are integrated into different materials and geometries. The thesis describes integration related issues of InAs, the epitaxial synthesis of the InAs nano-structures and summarizes experimental techniques for analysis of electrical properties of the integrated structures.

    Abstract : The overall aim of this thesis was to evaluate the outcome when treating children for displaced femoral fractures with external fixation.In a consecutive and prospective study during the period 1993-2000, 96 children aged 3-15 years with 98 displaced femoral fractures were treated with external fixation and early mobilisation. The mean age was 8. READ MORE

  5. 3. Three-Dimensional Metal-Semiconductor Heterostructures for Device Applications

    Author : Lars-Erik Wernersson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Schottky contacts; space-charge spectroscopy; ballistic transport; Coulomb repulsion; electron interference; resonant tunnelling; lateral confinement; heterojunction permeable base transistor; resonant tunnelling diodes; Fysicumarkivet A:1998:Wernersson; Fysik; Physics; resonant tun; epitaxial overgrowth;

    Abstract : Fabrication and characterisation of buried metal contacts in compound semiconductors are demonstrated. The contacts have been investigated due to their usage both as gates in transistors and as active or passive elements in novel devices. READ MORE

  6. 4. Epitaxial Lateral Overgrowth of Indium Phosphide and Its Application in Heteroepitaxy

    Author : Yanting Sun; KTH; []
    Keywords : electronics; electrical; material science;

    Abstract : Monolithic integration of optoelectronics on silicon is adream. This thesis deals with the studies on the heteroepitaxyof indium phosphide on silicon substrate towards making thatdream come true. Materials growth issues, characterization anddefect identification are addressed. READ MORE

  7. 5. Cyclosporin A-induced gingival overgrowth in renal transplant patients : a clinical, histological and experimental study

    Author : Biniyam Wondimu; Karolinska Institutet; Karolinska Institutet; []
    Keywords : cyclosporin A gingival overgrowth gingival fibroblasts nephrotoxicity renal transplant saliva;

    Abstract : Cyclosporine A (CsA) is widely used as an effective immunosuppressive agent to prevent rejection of organ transplants, as well as in the treatment of patients with various autoimmune diseases. The clinical use of CsA, however, is associated with adverse side effects, including nephrotoxicity, hepatotoxicity, hypertension, and neurotoxicity as well as gingival overgrowth. READ MORE
