Simulation Studies of Plasmon Enhanced Evanescent Near-Field Optical Lithography

Sefa-Ntiri B., Docker P., Ward M.C., Prewett P.D., University of Birmingham, UK

Evanescent Near-Field Optical Lithography (ENFOL) is an inexpensive route to nanolithography, overcoming the diffraction limitations of conventional optical technology. This paper details modelling work developed by the authors, to produce a predictive model that can [...]

Quantification of Properties for Ferroelectric Thin Films Using Piezo-response Force Microscopy

Cain M.G., Lowe M.J., Cuenat A., Stewart M., Blackburn J., National Physical Laboratory, UK

Ferroelectric thin films are used within FE-RAM Memory devices, thermal imaging cameras and for new and emerging micro-integrated applications. Piezo Force Microscopy (PFM) is a method that can be used to probe (using a modified [...]

Acid Transformation of TiO2 Nanotubes to Nanoparticles

Bavykin D.V., Lapkin A.A., Friedrich J.M., Walsh F.C., University of Bath, UK

Transformation of TiO2 nanotubes in the presence of sulfuric acid to TiO2 nanoparticles was studied. The possible physico - chemical reasons for such transformations are critically discussed.

Novel Magnetic Separable Nano-Carriers For Chemical Catalysis & Bio-Catalysis

Tsanga S.C., Tamb K., Gaoa X., Yua C.H., Yua K.K.M., Yeunga C.M.Y., Yua C.H., Yua K.K.M., University of Reading, UK

Separation of nanosize catalyst from product in liquid phase has been a major problem in industry. Thus the facilitated separation of a small magnetic body carrying catalytically active species is of a tremendous interest however; [...]

A Novel Method of Fabricating Optical Gratings Using the One Step DRIE Process on SOI Wafers

Cooper A.W., Docker P.T., Ward M.C., The University of Birmingham, UK

This paper describes a novel technique for manufacturing optical gratings by using the one step DRIE (Deep Reactive Ion Etching) process. Using the notching effect documented in previous work when working with silicon on insulator [...]

Polymer-Controlled Growth of CdSe Nanoparticles into Micro- and Nanowires

Fahmi A.W., Oertel U., Steinert V., Moriarty P., Stamm M., University of Nottingham, UK

This work reports an easy and effective method to prepare CdSe semiconductors nanoparticles stabilised by using amphiphile diblock copolymer polystyrene-block-polyvinylpyridine [PS-b-P4VP] in nonaqueous medium. spin coating on native oxide Si-wafers showed a core-shell structure of [...]

NEMS Mass Sensor by Focused Ion Beam Fabrication

Boonliang B., Prewett P.D., Ward M.C.L., Docker P.T., Birmingham University, UK

Due to rising industrial demands (food, biology, control), there is a drive to develop smaller, more sensitive sensor-devices with real-time capability. The objective of this work is to utilise Focused Ion Beam (FIB) fabrication technology [...]

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 [...]

Anodisation of Thin Film Aluminium

Douglas C, Evans P, Pollard R.J., Queen's University, Belfast & Nanotec NI, UK

Anodisation of alumina is a promising route for the preparation of nano-templates where regular arrays of pores can be produced in foils using a two step anodisation process [1] and Figure 1. The integration of [...]

Ferroelectric Properties of FIB-prepared Single Crystal BaTiO3 Nanocapacitors

Schilling A., Saad MM., Baxter P., Adams TB., Bowman RM., Gregg JM., Morisson FD., Scott JF., Queen's University, Belfast & Nanotec NI, UK

Measurements on free standing single crystal barium strontium titanate capacitors made using focused ion beam micromachining with thicknesses down to 75 nm, show a dielectric response typical of large single crystals, rather than conventional thin [...]
