1. 1. Liquid Exfoliation of Molybdenum Disulfide for Inkjet Printing

   Författare :Viviane Forsberg; Håkan Olin; Renyun Zhang; Magnus Hummelgård; Joakim Bäckström; Li Yang; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MoS2; Exfoliation; Inkjet Printing; 2D materials; Environmental Friendly; TMD; thin films; industrial printing; 2D inks; printed electronics; thin films carrier mobility; large-area electronics; graphene analogues; solar cells;

   Sammanfattning : Since the discovery of graphene, substantial effort has been put toward the synthesis and production of 2D materials. Developing scalable methods for the production of high-quality exfoliated nanosheets has proved a significant challenge. LÄS MER

3. 2. Charge Transport in Single-crystalline CVD Diamond

   Författare :Markus Gabrysch; Jan Isberg; Mats Leijon; Milos Nesladek; Uppsala universitet; []
   Nyckelord :CVD diamond; wide-bandgap semiconductor; single-crystalline diamond; carrier transport; time-of-flight; drift velocity; mobility; compensation; pair-creation; electronic devices; diamond detector; diamond diode;

   Sammanfattning : Diamond is a semiconductor with many superior material properties such as high breakdown field, high saturation velocity, high carrier mobilities and the highest thermal conductivity of all materials. These extreme properties, as compared to other (wide bandgap) semiconductors, make it desirable to develop single-crystalline epitaxial diamond films for electronic device and detector applications.

4. 3. Electrical Transport in Nanoparticle Thin Films of Gold and Indium Tin Oxide

   Författare :Jesper Ederth; Knut Deppert; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Electrical transport; Nanoparticle; Nanocrystalline; Materialvetenskap; Materials science; Teknisk materialvetenskap; English; engelska;

   Sammanfattning : Electrical transport properties of nanoparticle gold films made by the gas evaporation method were analysed using resistivity measurements. Low temperature electrical transport measurements showed a cross-over from a temperature range dominated by inelastic scattering to a temperature range dominated by elastic scattering, presumably by grain boundaries.

5. 4. Electrical Characterization of Integrated InAs Nano-Structures

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

   Sammanfattning : 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.

7. 5. Growth and Characterization of Metastable Wide Band-Gap Al1-xInxN Epilayers

   Författare :Timo Seppänen; Robert F. Davis; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thin film; Magnetron Sputter Epitaxy MSE ; Physics; Fysik;

   Sammanfattning : InN to 6.2 eV for AlN, which opens possibilities to engineer opto-electronic devices operating from infra-red to deep ultra-violet wavelengths. Al1-xInxN with the alloy composition x~0.2 can also be used as a lattice-matched electron confinement layer for GaN based electronic devices. LÄS MER
