| Abstract | |
Based on the Dirac equation, the behavior of relativistic electrons which tunnel a potential barrier of height V-0 for incoming energies between V-0 and V-0 + m is studied by using the wave packet formalism. The choice of this incoming energy zone guarantees that only electrons participate in the tunneling process. In the opaque limit, as shown in a previous analysis, the transit velocity is proportional to the barrier width and for relativistic potential tends to a constant value greater than c. In this paper, a new numerical study shows a very surprising result: superluminal transmissions are also evident for thin barriers. (AU) | |
