The Hayabusa spacecraft successfully recovered dust particles from the surface of near-Earth asteroid 25143 Itokawa. Synchrotron-radiation x-ray diffraction and transmission and scanning electron microscope analyses indicate that the mineralogy and mineral chemistry of the Itokawa dust particles are identical to those of thermally metamorphosed LL… (More)
In this paper, we propose a comprehensive model to express nMOSFET threshold voltage shift induced by the stress, ranging from high tensile one to high compressive one. Using this model, the quantum confinement effect is shown to play an important role to cause the threshold voltage shift as large as about 80mV induced by high-film-stress CESL.
