This letter addresses two difficult challenges for transition metal oxide resistive random access memories (ReRAMs)—sensitivity to operation temperature and random fluctuation of resistance value. A careful study of a WOx ReRAM array reveals that these devices are unstable and their read currents fluctuate with time due to random telegraph noise and structure relaxation. Consequently, even after careful...
Since vernier permanent-magnet machine (VPMM) has the merit of low-speed operation with high output torque due to the “magnetic-gearing” effect [1], they have been used in the direct-drive applications such as wind power generator, electric vehicle/hybrid electric vehicle (EV/HEV) [2,3].
The Y-doped ZnO nanocrystalline films were deposited on the glass substrates by sol-gel method. X-ray diffraction measurements of the films showed the same wurtzite hexagonal structure and preferential orientation along the c-axis. The grain size of the ZnO films was decreased by the doping of Y. Temperature dependence resistivity showed a semiconductor transport behavior for the nanocrystalline films...
The major increase in discharge duration and plasma energy in future fusion device will give rise to important plasma-material interaction effects that will critically influence plasma performance and safety operation. Power deposition on the first wall leads to erosion of the material and contamination of plasma. It is important to measure the temperature distribution for inferring the local heat...
