The formation of epitaxially stabilized nickel and cobalt silicides by pulsed laser annealing
… annealing has been investigated. Thermally grown NiSi and CoSi and Si<111> substrate were irradiated with laser pulses in the energy density range between 0.4 - 1.0 J/cm² in an attempt to produce epitaxially stabilized silicides. The analysis was carried out using well established RBS and …

Marker studies of nickel silicide formation
… of thin films of nickel silicides (Ni2Si and NiSi) from nickel and amorphous silicon has been investigated using 31Si radioactive tracer and inert marker techniques. Samples were prepared by vacuum deposition of thin films of nickel and silicon, followed by thermal annealing to effect silicide …

MHC Class I diversity influences haematozoon infection intensity in the polymorphic black sparrowhawk (Accipiter melanoleucus)
… of blood parasite load (for Haemoproteus nisi and Leucocytozoon toddi); the study tested the relationship between (i) allelic diversity and individual parasite load and (ii) specific alleles and individual parasite load using a Generalized Linear Model framework. Seven different, …

Characterization of heat-treated nickel and gold films on silicon single crystals
… The crystallites were identified as NiSi<sub>2</sub>.</p> <p>Diffusion appeared to be important to the formation of the NiSi<sub>2</sub>. Therefore, in-depth Auger electron spectroscopy was used to study the diffusion kinetics of nickel in silicon. The activation energy for diffusion …

Platform for monolithic integration of III-V devices with Si CMOS technology
… on Si/III-V films are investigated and the NiSi/Si/III-V structure is found to be optimal. This structure is composed of a standard NiSi/Si interface and novel Si/III-V interface. Specific contact resistivity of the double hetero-interface stack can be tuned by controlling Si/IIIV band …

Use of solution-state nuclear magnetic resonance spectroscopy to determine the structures of medicinally relevant peptides and proteins
… activity in addition to bactericidal activity. Nisin, the prototypical lantibiotic, was studied in the context of the immunity protein, NisI, which is believed to confer immunity against lysis to the producing organism. The final system was phosphite dehydrogenase, an enzyme putatively useful in …

Fabrication of silicon-based nano-structures and their scaling effects on mechanical and electrical properties
… electron transport, a set of nickel monosilicde (NiSi) nanolines with feature size down to 15 nm was fabricated. The linewidth effect on nickel silicide formation has been studied using high-resolution transmission electron microscopy (HRTEM) for microstructural analysis. Four point probe …

Physical investigations of novel materials and structures for Nano-MOSFETs
… has been studied in detail as a function of NiSi thickness, implantation energy and dose, as well as process conditions for the formation of NiSi. It is shown that dopant concentrations as high as the solid solubility and lateral dopant slopes of 1-2nm/dec at the NiSi/Si-contact interface can …

Metallic thin film on SiGe/Si substrates
… Si0.8Ge0.2 substrates to form thin, amorphous NiSi-like, NiGe-like and NiSi0.8Ge0.2-like layers at RT on both clean and hydrogen terminated surfaces. Upon annealing, they transformed to NiSi2, NiGe and Ni(Si1-yGey)2 (y<0.2) phases, respectively. Continuous films at RT became 3D rectangular …

Strained and unstrained silicon nanowire array MOSFETs : fabrication and physical analysis
… of the silicided segment lengths. By introducing NiSi the S/D resistance was reduced compared to conventional NW-array p-MOSFETs. NiSi contacts showed an orientation dependence, resulting in lower S/D resistance for <100> NWs compared to <110>. As a consequence NW p-MOSFETs with <100> channels …

Characterisation of novel bacteriocins from canine sources
… investigates the heterologous expression of the nisin immunity proteins NisI and NisFEG, and the nisin resistance proteins Nsr and NsrFP, in three Lactococcus lactis strains. One strain is nisin sensitive (MG1614), one is immune (NZ9800), and the third is both nisin producing and immune (NZ9700). …
