Switching Behaviour (switching + behaviour)
Selected AbstractsPositive magnetoresistance in TixW1-xSe2 (x = 0, 0.03) platelet crystalsCRYSTAL RESEARCH AND TECHNOLOGY, Issue 10 2006Sunil Kunjachan Abstract Layered transition metal dichalcogenide crystal, WSe2, has been grown by direct vapour transport technique. Titanium is used as a dopant in to the 2H type MX2 matrix. These crystals show positive magnetoresistance and a switching behaviour is observed at room temperature in the titanium-intercalated sample. The relative resistance change due to magnetic field for the doped sample is found to switch from 23.6% to 39.6% when the sample is rotated through 0° to 90°. (© 2006 WILEY-VCH Verlag GmbH & Co.

In the Netherlands, a new health insurance law was introduced in January 2006 making it easier to switch health insurer each year. Objective, The objective was to measure people's intention to switch health insurer and actual switching behaviour. We also examined whether some groups were less inclined to switch health insurer and/or had more difficulty to exert their intention to switch. Design, In October 2006, members of three Dutch panels indicated whether they intended to switch health insurer during that year's open enrolment period. In the beginning of 2007, the same people were asked whether they indeed switched health insurer. Results, Only 1% intended to switch health insurer. Women, older people, lower educated people, people who were insured for a longer period and people who reported a bad or moderate health were less inclined to switch health insurer. The amount of switching was higher among individuals who intended to switch (31%) than among individuals who did not know whether they would switch (7%) and individuals with no intention to switch (2%). Among those who intended to switch health insurer, women and people who reported a good health switched health insurer more often. The years of enrolment were also associated with actual switching behaviour. Discussion and Conclusions, We might have to temper the optimistic expectations on enhanced choice. Future research should determine why people do not switch health insurer when they intend to and which barriers they experience. [source] Reliability aspects of SiC Schottky diodesPHYSICA STATUS SOLIDI (A) APPLICATIONS AND MATERIALS SCIENCE, Issue 10 2009Matthias Holz Abstract In recent years, silicon carbide (SiC) high-voltage power devices have gained an ever-increasing market share. The fast development of new device concepts and technologies, e.g. for SiC Schottky diodes, has led to devices with superior switching behaviour, which renders SiC power devices especially favourable for high-frequency applications. As of today, SiC devices enter various fields like, e.g. server power supplies, solar inverters, and drives. These applications pose quite different requirements not only on the electrical properties, but also on the long-term reliability of the devices. In this paper, we describe in detail how Infineon's SiC Schottky diodes excel the reliability requirements. We point out how material properties, device design and packaging technology affect the overall device reliability and how they can be optimized. In addition, we describe measurement results after stress tests that go far beyond standard stress tests according to JEDEC. E.g., we show that SiC devices can safely be operated at high voltage slopes of 120 V/ns. In addition, we show that the use of high performance die attach further improves the device properties and reliability. (© 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) [source] | ||||||||||
