The resistivity of a quasi-one-dimensional structure fabricated without masks by 20-keV Ga+ focused ion beam (FIB) on crystalline Si substrates was investigated for the first time, along with an analysis of properties of implanted p+ layers. The junction depth of the 7?? off-axis implanted layer after annealing, which was measured by stain method, is 410 nm. The distribution profile was investigated...
A novel stress-sensitive nanocomposite that can be used as flexible force sensors with tailored sensitivity was fabricated. The nanocomposite consists of MWNTs as conductive filler and SBS as polymer matrix. Some electrical and mechanical properties of MWNT/SBS films were measured. A typical percolation phenomenon was observed with the MWNT/SBS composites. The elastic modulus and Poisson's ratio of...
Undoped Nanostructured Titanium Dioxide thin film (UN) and Cobalt doped nanostructured (CoDN) TiO2 thin film has successfully prepared using sol-gel method and deposited onto silicon and glass substrate by spin coating technique. Nanostructured TiO2 thin film were prepared at 0.1 M, 0.2 M, 0.3 M and 0.4 M, Co doped TiO2 thin film was prepared with additional of ion Co at 1 at%. The electrical and...
The sealed winding conformance test is often performed during the final acceptance test sequence for industrial motor stator insulation. The stator winding is first completely soaked with water, then receives a 10-minute insulation resistance (IR-io) measurement, followed by a 60-second high potential (hipot) test at 1.15 times rated line-to-line voltage (Vll). A 1-minute insulation resistance (IR-i)...
The optimization of the magnetic properties of materials for a wide range of technologies requires a dynamic iteration between synthesis, property measurements and the evaluation/control of microstructure (physical, chemical & magnetic) at the appropriate length scales. In addition, atomically engineered thin films and nanostructures offer new opportunities to elucidate the physics of magnetism,...
