Abstract

The transmission probabilities of an accurate and an approximate (triangular) Esaki barrier are evaluated. We show that the approximate results for transmission coefficients differ by orders of magnitude from the correct ones, however the approximate methods provide good results for physical quantities defined as ratios of transmission coefficients.
