Now, we can substitute all the values into the equation for the instantaneous current: This is the required equation for the instantaneous current in the circuit. Conclusion Capacitors store electrical energy when connected with alternating current (AC) sources. AC capacitance is determined by the si...
Schrodinger equationsiliconBy self-consistently solving the Schrdinger and Poisson equations, we have studied theoretically the current and capacitance characteristics of a metal–oxide–semiconductor structure consisting of an ultrathin oxide layer embedded between an n-silicon substrate and n+-...
which is expected to be larger than 1. In other words, m and AV compete with each other in determining SS. NC does not help good FETs The detailed physics of the equation in Fig. 2b can be “visualized” in Fig. 2c. As shown, when |CNC| is larger than COX, m wins the competit...
This equation is immediately recognizable as relating to a single-degree-of-freedom, damped harmonic oscillator, which is one of the most well-studied problems in engineering and physics. We know that we can compute from this expression the resonant frequency and quality factor of such an osc...
