WebCharge carrier density, also known as carrier concentration, denotes the number of charge carriers in per volume. In SI units, it is measured in m −3. As with any density, in principle it can depend on position. However, usually carrier concentration is given as a single number, and represents the average carrier density over the whole material. WebThe charge pumping current is directly related to the mean interface trap density in the channel, the size of the interface channel area, the frequency , and the pulse shape characterized by its rise and fall times. This makes the charge pumping method a perfect tool for the characterization of interface degradation. 4.1.3 Numerical Simulation reizdavanje certifikata zaba https://tycorp.net
