GATE DIELECTRIC BREAKDOWN PHYSICAL ANALYSIS AND STUDIES -2D MODELING OF BREAKDOWN THERMAL EFFECT
… oxide is indeed important to understand the soft breakdown (SBD) and hard breakdown (HBD) mechanisms of a narrow channel MOSFET. During HBD or under favorable condition of SBD, silicon epitaxy growth is observed at the cathode side of the MOSFET. This epitaxy growth is named dielectric …

Dielectric Breakdown of Silver Azide
The breakdown of single crystals of heavy metal azides has been investigated. In silver azide, the low-field conduction is by mobile interstitial cations and their enthalpies ,of formation and hopping have been determined from the Arrhenius plot of the conductivity. Based on AC conductivity · …

Virtual workplaces : when metaphors breakdown
… the lens of metaphors, this research focuses on breakdowns between collaborative work and the environment in which work occurs. If what we understand and predict is based on what we already know, then by examining the breakdowns between design and use of collaborative environments we can …

Sucrose breakdown in the potato tuber
In dieser Arbeit wurden verschiedene Ansätze verfolgt, um das Verständnis des Saccharose-zu-Stärke Stoffwechselweges in sich entwickelnden Kartoffelknollen zu untersuchen. Zunächst wurde ein induzierbares Genexpressions-System aus dem Schimmelpilz Aspergillus nidulans für die Untersuchung des …

A study of U.S. adoption breakdown : exploring current factors associated with breakdown and challenging times in adoption adjustment.
Adoption breakdown often results in devastating effects for the family and child. Children and parents who experience adoption breakdown suffer adverse residual effects of a traumatic experience. Given the dire outcomes following adoption breakdown, additional research is needed to continue to …

Degradation and Breakdown of Ultrathin Gate Oxide
… oxides, a new type of failure mode, soft breakdown, has been observed. The characteristics of this kind of failure are often identified by a large increase of gate signal noise level. It has been proposed that there is a threshold power that divides soft and hard breakdown. In this thesis, …

Contributions to the theory of statistical breakdown
The theory of statistical breakdown is studied from two different angles. Firstly, the finite sample breakdown points of estimators are found to be inherently related to their tail performances. This connection provides persuasive new evidence for the importance of the breakdown point of estimators …

The evolution and breakdown of submesoscale instabilities
Ocean submesoscales are the subject of increasing focus in the oceanographic literature; with instrumentation now more capable of observing them in situ and numerical models now able to reach the resolution required to more fully capture them. Submesoscales are typified by horizontal spatial scales …

Optical breakdown acoustics : transduction and sensing underwater
… monitoring. In this thesis, I develop optical breakdown as an acoustic source for non-contact measurements of underwater structures. Optical breakdown occurs when a high-power laser is focused to a small spot, causing nonlinear interactions between the light and water. A compact plasma forms at …

RF breakdown effects in microwave power amplifiers
… amplifiers can lead to hot-electron-induced "breakdown" in these devices. This thesis explores issues related to breakdown in the Transcom TC2571 PHEMT, and the effects this has on the Draper Laboratory 2.3 GHz microwave power amplifier in which the transistor is used. Characterization of …

Impulse electrical breakdown of high-purity water
Experiments have been conducted on the electrical breakdown of high-purity water and water mixtures. The electrical regime of interest has been carefully defined and documented to consist of electrical impulses with approximately microsecond rise time and fall time greater than 65 microseconds, on …
