Strained superlattices (SSLs) are typically found inside the p-n junction area of semiconductor devices and consist of very thin alternating layers of different material. There exists a small lattice mismatch between these ...

Herein we report the formation of multi-layered arrays of vertically aligned and close packed semiconductor nanorods in perfect registry at a substrate using electric field assisted assembly. The collective properties of ...

lasmons in the visible/UV energy regime have attracted great attention, especially in nano-materials, with regards to applications in opto-electronics and light harvesting; tailored enhancement of such plasmons is of ...

Colloidal carbon spheres were synthesized by the carbonization of squalane, a nonvolatile hydrocarbon solvent, in supercritical carbon dioxide. Precise pressure modulation of the fluid medium led to size controlled growth ...

Irish students’ interest and enjoyment of science deteriorates as they progress through formal education and subsequently enrolments in the physical sciences at second and third level education are low. Research in science ...

A challenge in molecular electronics is to control the strength of the molecule–electrode coupling to optimize device performance. Here we show that non-covalent contacts between the active molecular component (in this ...

A transmission electron microscope was used to characterize a powder form of hexagonally-ordered mesoporous silica material. The structural symmetry built into this amorphous material allowed one to obtain three characteristic ...

This paper reports initial experimentation of a dual beam flow velocity estimation setup based on optical coherence tomography (OCT) for biomedical applications. The proposed work incorporates a low cost switching mechanism ...

This assertion underscores the importance of haematological dynamic assessment, which can benefit greatly from non-invasive high-resolution imaging of blood flow especially at the microvascular level. This importance is ...

This thesis describes work on single-photon pair creation, entanglement and entanglement measurement; single-photon spectral narrowing for atomic interaction; and single-photon detection and spectral analysis. The systems ...
