CrAlYN nanolayered coatings of greatly enhanced thermal stability have been developed by doping with levels of Y up to 9at.%. This prevented the complete dissolution of the layered structure after annealing at 1100°C in Ar for 1h, commonly observed in coatings with little or no Y content, although the bilayer period increased from ~5nm to ~10nm. The improved thermal stability is attributed to the...
Novel cyclotriphosphazene based lubricant oil (Lube-PN) for heat-assisted magnetic recording media was synthesized by reacting hexachlorocyclotriphosphazene with pentafluorophenol, followed by treatment with a hydroxy-terminated perfluoropolyether in a high yield. Its chemical structure was confirmed by 1H and 31P NMR. Its properties including viscosity, thermal stability, tribology, laser resistance...
We present a novel selector made of doped-chalcogenide material. This selector not only achieves low holding voltage (0.2 V) and large on/off ratio (>107), but also exhibits the high on-current density (>1.6 MA/cm2) and large hysteresis window (1.2 V). Besides, excellent selector performances with ultra-low off-state leakage current (10 pA), high switching speed (<10 ns), high endurance (>10...
