Schottky diodes often exhibit anomalous current-voltage characteristics at low temperatures with temperature dependent ideality factors and apparent barrier heights evaluated for the thermionic emission. In this paper theoretical expressions are first presented for the temperature dependencies of the ideality factor and the apparent barrier height for the thermionic-field (T-F) emission, including the bias dependence of barrier height. Expressions are also presented to evaluate the characteristic energy Eoo and the bias dependence of barrier height from the temperature dependence of the ideality factor. Model calculations have been performed using these expressions, and their results are compared with the available experimental data. It is shown that the mechanism responsible for the temperature dependent ideality factors and apparent barrier heights often is the T-F emission with anomalously high characteristic energies. The possible causes of the high characteristic energies are discussed.
