Quadrupole electromagnets have been developed with a hollow coil produced using an improved periodic reverse electroforming. These will be installed in each of the drift tubes of the DTL (324 MHz) as part of the JAERI/ KEK Joint Project at the high-intensity proton accelerator facility. Measurements of the magnets’ properties were found to be consistent with computer-calculated estimated. The d...
The local interplay between the ionic and electronic transport in NiO is explored using correlative imaging by first-order reversal curve measurements in current-voltage and electrochemical strain microscopy. Electronic current and electromechanical response are observed in reversible and electroforming regime. These studies provide insight into local mechanisms of electroresistive phenomena in...
Metal-insulator-metal (MIM) structures based on titanium dioxide have demonstrated reversible and non-volatile resistance-switching behavior and have been identified with the concept of the memristor. Microphysical studies suggest that the development of sub-oxide phases in the material drives the resistance changes. The creation of these phases, however, has a number of negative effects such a...
Organolead halide perovskites are used for low-operating-voltage multilevel resistive switching. Ag/CH3 NH3 PbI3 /Pt cells exhibit electroforming-free resistive switching at an electric field of 3.25 × 10(3) V cm(-1) for four distinguishable ON-state resistance levels. The migration of iodine interstitials and vacancies with low activation energies is responsible for the low-electric-field resi...
Fabrication by the ‘Laser-LIGA’ process of three-dimensional structures for micro-fluidic devices is investigated. Polymer moulds are formed by projection ablation using an excimer laser operating at 248 nm wavelength. The moulds are replicated by electroforming — as in conventional X-ray LIGA — to produce fixed and freely moving nickel microturbine parts with heights of 150 lm, wall angles of ...
