An efficient analytical model for calculating trapped charge in amorphous silicon

Yao-Tsung Tsai; Kuo-Don Hong; Yin-Lun Yuan IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 1994

We present an efficient analytical model for calculating the trapped-charge density as a function of Fermi energy based on two exponential regions for density-of-states distribution in hydrogenated amorphous silicon. In this efficient model, the trapped-charge density is calculated without numerical integration and without curve fitting as a function of Fermi energy. Comparisons between the analytical and the numerical models have ...


Identification and control of crystallization dynamics during sheet polymer extrusion

C. Batur; L. Thananchai Proceedings of the 1997 American Control Conference (Cat. No.97CH36041), 1997

Crystallinity control for polymer sheet extrusion processes is considered. An analytical model for the crystallinity dynamics is derived. This development is based on the continuity, momentum, energy and crystallinity equations. It is shown that the crystallinity dynamics can be linearized around a normal operating point. Based on the linearized model, the crystallinity dynamics are identified and a pole placement control ...

Recent investigations have led to the discovery of a new class of ferroelectric polymers-the odd-numbered nylons. X-ray diffraction and infrared absorbance (Fourier-transform infrared) studies of nylon 11 and nylon 7 films with 3-D orientation (texture) provided an understanding of the polarization process in these polymers. More importantly, these studies led to an electroprocessing technique which allowed for the stabilization of ...

The CdSe nanoparticles have been synthesized by hot-injection method, and thermal annealing was used to improve the crystallinity of synthesized nanoparticles and reconstruct the surface of nanoparticles. The synthesized and annealed CdSe nanoparticles were characterized by TEM, XRD and PL spectra.

J. Huck; A. Bondeau; G. Noyel; L. Jorat IEEE Transactions on Electrical Insulation, 1988

Temperature dependence of the viscosity of many glass-forming liquids is investigated over a wide range of temperatures (100 to 1700 K). It is shown that the three Vogel-Fulcher coefficients are not constant but exhibit regular variations versus temperature over the entire range 10-3 to 1012 Pl. This property is consistent with the nonlinear variations of the free-volume in the Cohen ...

  • Effects of Melting on Faulting and Continental Deformation

    The presence of melt is closely related to the localization of deformation in faults and shear zones in a variety of tectonic settings. This relationship is observed on length scales from the outcrop to plate boundary faults to orogens. However, the question of whether melting induces localization, or localization creates a pathway for melts, can rarely be answered from field observations alone. Experimental studies show that rock strength decreases exponentially with increasing volume percentage of melt. This suggests that melting facilitates strain localization where deformation would be homogeneous in the absence of melt. Yet, the extrapolation of experimental relationships between rock strength and melt content to natural conditions at depth in the lithosphere remains speculative, largely because the grain-scale processes underlying dramatic weakening at small amounts of melt have yet to be investigated in crustal rocks. New geochronological methods for dating minerals that crystallized during deformation in the presence of melt have the potential to constrain the time lag between the onset of melting and deformation in naturally deformed anatectic rocks. An indirect, but clear answer to the question of whether melting induces strain localization on a regional scale comes from numerical models of orogenesis which can be run in the presence or absence of low-viscosity domains that approximate the mechanical behavior of partially melted rock. These models show that melting induces lateral flow of anatectic crust within horizontal channels usually situated at the base of the continental crust. These channels have strong vertical strain gradients, especially at their boundaries where shear zones accommodate lateral extrusion of the anatectic rock in between. Together with their bounding shear zones, these flow channels form a new class of faults, which we term " ;extrusional faults." Extrusional faults containing long-lived melt (tens of millions of years) can support large, broadly distributed topographic loads such as orogenic plateaus and can exhume deeply buried rocks from beneath orogens. In contrast, strike-slip and oblique-slip faults serve as steep conduits for the rapid ascent, differentiation, and crystallization of melt. The relatively short residence time of melts in such moderately to steeply dipping fault systems can lead to episodic motion, with long periods of creep punctuated by shorter periods of melt veining, magmatic activity, and/or faster slip.
