Magnetically soft/hard exchange-coupled Ni80Fe20 /Si3N4 /Sm40Fe60 and Ni80Fe20 /mixture/ Sm40Fe60 layered structures with induced in-plane uniaxial anisotropy were deposited by sputtering on Si ~100! substrates. The interfacial exchange coupling strength between the soft and hard layers was tailored by inserting a thin nonmagnetic insulating Si3N4 layer or by varying interfacial mixture of NiFe...

Two compositions of ZrB2-based ceramic composites containing Si3N4, Al2O3 and Y2O3 have been hot-pressed at different temperatures between 1673 and 1773 K for 60 min in vacuum. The densification behavior of the composites was examined during the sintering process. The microstructures of the composites were characterized by scanning electron microscopy, and the crystalline phases were identified...

In this paper, a zinc oxide (ZnO) nanotube, fabricated by the hydrothermal growth method on triple-junction (T-J) solar cell devices to enhance efficiency, is investigated. Compared to those of bare T-J solar cells (without antireflection (AR) coating) and solar cells with Si3N4 AR coatings, the experimental results show that the T-J solar cells, which use a ZnO nanotube as an AR coating, have ...

For integrated passive device (IPD) applications, we have successfully developed and characterized metalinsulator-metal (MIM) capacitors with 2000 Å plasma-enhanced chemical vapor deposition (PECVD) silicon nitride which are deposited with the SiH4/NH3 gas mixing rate, working pressure, and RF power of PECVD at 250oC. Five PECVD process parameters are designed to lower the refractive index and ...
