TRAVERSAL TIME ANALYSIS IN RESONANT-TUNNELING STRUCTURES

The wave function is used to calculate the traversal time of a resonan t tunnelling structure. It is established that the traversal time incr eases with increasing width and height of the barriers as well as the width of the well. Based on the real part of the quantum mechanical wa ve impedance, the traversal time is calculated using the transmission matrix approach and the results are in good agreement with other repor ted theoretical and experimental results. Traversal times as a functio n of applied voltage and Fermi energy level are calculated.
