2. 1. Miniaturized localized surface plasmon resonance biosensors

   Author : Si Chen; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; colloidal lithography; Surface plasmon resonance; biosensing; electron beam lithography; single molecule; hyperspectral imaging; photo functionalization;

   Abstract : Abstract Reliable and sensitive biosensors are required for fast and accurate diagnostics. Localized surface plasmon resonances (LSPRs) in noble-metal nanoparticles possess very high refractive index sensitivity close to the metal surface and therefore constitute an attractive biosensing platform.

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Semiconductor surfaces; Si 111 ; Ge 111 ; manganese; Mn; silicides; germanides; atomic structure; electronic structure; magnetic properties; LEED; ARPES; XPS; core-level spectroscopy; STM; STS; XMCD; Physics; Fysik;

   Abstract : The research presented in this thesis concerns experimental studies of thin manganese silicide and germanide layers, grown by solid phase epitaxy on the Si(111)7×7 and the Ge(111)c(2×8) surfaces, respectively. The atomic and electronic structures, as well as growth modes of the epitaxial Mn-Si and Mn-Ge layers, were investigated by low-energy electron diffraction (LEED), angle-resolved photoelectron spectroscopy (ARPES), core-level spectroscopy (CLS), and scanning tunneling microscopy and spectroscopy (STM and STS).

5. 3. Electronic Structure and Film Morphology Studies of PTCDI on Metal/Semiconductor Surfaces

   Author : Christian Emanuelsson; Hanmin Zhang; Lars Johansson; Ellen Moons; Mats Ahmadi Götelid; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; PTCDI; STM; LEED; XPS; UPS; NEXAFS; Organic Films; Semicondcutor Surfaces; Electronic Structure; Molecular Interactions; Film Morphology; Physics; Fysik;

   Abstract : Organic semiconductors have received increasing attention over the last decades as potential alternatives for inorganic semiconductors. The properties of these films are highly dependent on their structural order. READ MORE

6. 4. Growth and Characterization of Ti-Si-N Thin Films

   Author : Axel Flink; Lars Hultman; Paul Mayrhofer; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Analytical transmission electron microscopy; Arc; Sputtering; Hard coatings; Multilayer Cutting inserts; analytisk transmissionselektronmikroskopi; ytbeläggningar; skärande; bearbetning; Ti-Si-N; arcförångning; sputtring; Material physics with surface physics; Materialfysik med ytfysik;

   Abstract : Utvecklingen inom materialforskningen går mot att framställa avancerade material vilka är skräddarsydda för olika tillämpningar. Detta har medfört att det blir allt mer populärt att belägga ytor med ett eller flera tunna lager med syfte att förbättra materialegenskaperna. READ MORE
