metal-oxide-semiconductor field effect transistorThis paper investigates the effects of a dielectric-constant mismatch between gate dielectric and silicon substrate on the capacitance-voltage curve of high-K MOS structures, numerically, via fully self-consistent solutions of Schrdinger and Poisson equations...
A circuit is provided whereby varactor diode is placed in parallel with a capacitance of either the sample or reference cell of a dielectric constant detector. At least the circuitry for applying a voltage to the varactor diode is located outside of the oven in which a dielectric constant detec...
The dielectric constant of AlON has been calculated from the slope of the plot of capacitance versus capacitor area. The value of 11 has been obtained ... A Poyai,W Bunjongpru,N Klunngien,... - 《Materials Science in Semiconductor Processing》 被引量: 5发表: 2008年 Contributions to Die...
In other terms, this indicates that the dielectric properties of PTEB/PTEBS have a profound effect on the exciton Bohr radius. The dielectric-constant effect on the excitonic energy levels of PTEB/PTEBS can be more immediately understood from its impact on the exciton's Bohr radius498where ...
We demonstrate a method for quantitatively probing the local low-frequency dielectric constant of thin insulating films by nanoscale capacitance microscopy. The calibrated capacitance-distance curves are measured on the dielectric film and analyzed by using a tip-sample capacitance model here proposed. App...
creating an electric field. The dielectric material prevents charges from flowing across the gap and enhances the electric field and charge storage. Capacitance is proportional to the plate area, inversely proportional to the distance between them, and directly proportional to the dielectric constant. ...
Describe how the following factors directly or indirectly affect the capacitance of a capacitor. a. Dielectric constant. b. Plate distance. c. Plate area. What is a capacitor in simple terms? What would be an example of one? Define a capacitor. Why dielectric constant decreases with the...
We analyze the determination of the dielectric constant of macroscopic solid samples in a nondestructive way from measurements of the capacitance between a pointer electrode and the sample's surface. We assembled an experimental device and found that an accuracy of 1% or better can be attained with...
where Cm and Cv are capacitance of the material and a vacuum, respectively. Because dielectric material affects the force with which two oppositely charged plates attract each other, the dielectric constant may also be defined as the relative effect of the medium on this force of attraction, acco...
Specifically, their intrinsic dielectric constants (ε') are calculated by impedance spectroscopy from the values of the obtained bulk capacitances. For CaMnO, that does not show charge-order, the measured intrinsic dielectric constant is 14. The Pr doping induces charge-order in the system, and...
