Abstract
The generalized tunneling formula with the simple model for the broadening in the contacts
gives surprisingly good results for the majority of RTD structures. It is just as fast as the
standard coherent tunneling simulators and much more versatile. It is easily generalized to
multi-band and multidimensional models. The multi-band generalization of the theory and the
effect of the optical potential are described.
