Analytical expressions of transmission coefficient and tunneling time of electrons incident on a heterostructure grown on an anisotropic material are derived by solving the effective-mass equation including off-diagonal effective-mass tensor elements. It is assumed that the direction of propagation of the...

tunnel through the barrier. The tunneling current is defined as the ratio of the current density emerging from the barrier divided by the current density incident on the barrier. If this transmission coefficient across the barrier is a non-zero value, then there exists a finite possibility that ...
In the tunneling limit, the voltage dependence of can be deduced by using the free-electron density of states and the Wentzel–Kramers–Brillouin (WKB) transmission coefficient28 and by considering a total potential including the potential barrier U(z) and the biasing energy Ubias(z, V) =...
