Carbon NanoDots for Selective Optical Cation Detection

Buiculescu R., Fouskaki M., Chaniotakis N.A., University of Crete, GR

In the present work, custom designed and synthesized carbon nanodots (C-dots) with cation selective functional organic ligands (carboxyl or amino) are used for the optical detection of cations. The ligands on the surface are able [...]

A facile block copolymer inclusion technique for large scale monodisperse hexagonal arrays of superparamagnetic iron oxides nanodots

Ghoshal T., Maity T., Godsell J.F., Roy S., Morris M.A., University College Cork, IE

We demonstrate a simple and cost-effective route, based around block copolymer patterning, to create dense arrays of highly ordered iron oxide nanodots at substrate surface. The methodology creates hexagonally arranged features via a process of [...]

Production of Nanodots by Ion Sputtering on Mechanical Polished (110) Si-Substrates

Ballesteros C., Rodríguez T., Rodríguez T., Universidad Carlos III de Madrid, ES

We report a new method to deposit Cu nanocrystals by 5kV Ar+ ion sputtering of Cu metallic ribbons at glazing incidence, 8º, on top of (110) Si-substrates mechanical polished down to a 0.1 μm finish. [...]

Preparation of PZT nanodots on Nano-Templated Substrates

McMillen M.J.A., Lookman A., Douglas C, Evans P, Bowman R.M., Gregg J.M., Pollard R.J., Queen's University, Belfast & Nanotec NI, UK

There is considerable interest in creation of nanoscale capacitor arrays. For example, in FeRAM technology, which has great potential, significant capacitor cell size reduction and transition to 3D structures, can be achieved within existing CMOS [...]

Multi-Tunnel-Junction Memory : Analyses of Feasibility for Non-Volatile Memory Applications

Le Carval G., Le Royer C., Le Carval G., Le Royer C., Sanquer M., CEA-LETI, FR

MOSFET Memories based on quantum dots have been investigated extensively because of their promising applications to non-volatile and low voltage memories. Among these memories, the Multi-Tunnel-Junction Memory (MTJM) appears to be a promising concept for [...]
