In VO2, which is a promising strongly correlated material of electro-optics, temperature-dependent electrical transport properties were investigated by using ordinary Hall effect measurement. The interesting variation on the near boundary of insulator-to-metal transition was observed.
The magnetic thermo-sensitive materials such as iron oxide particles and their colloids have been widely studied in local hyperthermia [1, 2]. Some researchers have been tried to apply the composite sheet instead of particles or their colloids to healing of skin infections including hyperthermia-aided immunotherapy [3, 4]. To healing of skin wound or tumor, the temperature over 43°C can create an...
Mismatch of analog circuits designed for mobile devices are studied with nanoprobing, pattern density, and inline monitoring using a 28LP SoC technology. Active layer density was found to be the root cause of high mismatch variation. Design guidelines, along with an interleaved design, are shown to improve mismatch for a given process flow.
Isothermal annealing above 1250 °C has been reported to reduce the dislocation density in multicrystalline silicon (mc-Si), presumably by pairwise dislocation annihilation. However, this high-temperature process may also cause significant impurity contamination, canceling out the positive effect of dislocation density reduction on cell performance. Here, efforts are made to annihilate dislocations...
The electrical and structural properties of platinum silicided p-type Schottky barrier metal-oxide-semiconductor field-effect transistors with physical gate lengths scaled down to 20 nm have been investigated. Constant built-in potential clipped at source/drain contacts for shorter channel length is responsible for negative shift of threshold voltage with decreasing gate length.
