We report a combined experimental and theoretical study of the compression of a solid foam coated with a thin elastic film. Past a critical compression threshold, a pattern of localized folds emerges with a characteristic size that is imposed by an instability of the thin surface film. We perform optical surface measu…
A model that takes into account the distribution of domain walls over natural frequencies and relaxation times (or activation energies) is proposed. It is demonstrated that the function of the distribution of domain walls over natural frequencies and relaxation times ƒ(ω0, τ) (or potential barriers ƒ(ω0, W 0)) can be…
BEOL reliability becomes increasing important issues as device dimensions are scaled for the Cu/low-k interconnects, including electromigration (EM), stress migration (SM), inter-line leakage, breakdown and time-dependent dielectric breakdown (TDDB) characteristics of low-k dielectrics, and plasma-process induced dama…
Silicon electron field emitters may be attractive for numerous applications, mostly due to their compatibility with the dominating Si-based solid state microand nanoelectronics. The technology of nanostructure formation through a laser radiation (LR) on Si surface for the electron field emitter is proposed. N-type Si…
The melt-electrospinning setup was designed in this paper. The temperature of every part in the setup,, including injector, nozzle, spinning space and collection target can be measured accurately by thermocouple or infrared radiation thermometers. The study on phenomena and properties of exploration for melt-electrosp…
The alpha-MoO3, h-MoO3and Mo4O11oxides are formed by low-temperature chemical synthesis from water-based solutions by different precipators. Phase purity and high crystallinity of final products are confirmed with XRD and TEM analysis. Spectral properties of molybdenum oxide nanocrystals are measured with IR and Raman…

In this paper, ZnO varistor+Al2O3ceramic+ZnO varistor insulators were made, in which the conductivity and permittivity of ZnO varistors were controlled by changing its voltage gradient. Then the influences of conductivity and permittivity of ZnO varistors on the DC and pulsed surface flashover voltage in vacuum were e…
This paper deduced the relationship of transmembrane voltage on cell membrane and frequency by solving the Laplace's equation. The value of transmembrane voltage will decrease when the frequency of outer electric field increases, and this decrease will be faster if the frequency exceeds a certain frequency band. The t…

Upstream Electromigration (EM) was studied on different multiple via structures. Better EM performance of structure with more via was observed. Via layout affects the current density distribution and resistance change under EM stress. Failure analysis showed different EM failure modes in these structures. EM performan…
Based on transfer function theory, pulse propagation model of partial discharge in dry-type transformer with subsection and layer windings is established, and the voltage transfer-functions are gained from the simulation prototype, which are fitted with rational functions by the vector fitting and synthesized by lumpe…

The authors demonstrated decoration of Ru nanoparticles on the surface of double-walled CNTs (DWCNTs) using a chemical process and studied their field emission properties. Ru is more stable than the low work function alkali metals when exposed to oxygen. Moreover, the melting point of Ru is much higher than that of Ru…
Aiming at the harsh electromagnetic environment, this paper presents a new method to extract partial discharge signal, which using fast Fourier transform suppress discrete spectrum interference, and then use discrete wavelet transform delete the residual noise all together. Further more, there is also bring out how to…
