A generalized Norde plot for reverse biased Schottky contacts
When a metal makes intimate contact with a semiconductor material, a Schottky barrier may be created. The Schottky contact has many important applications in the IC electronics field. The parameters of such contacts can be determined from their current-voltage (I-V) characteristics. The literature contains many proposals for extracting the contact parameters using graphical methods. However, such methods are generally applicable only to contacts with a forward bias, whereas many Schottky contacts actually operate under a reverse bias. Accordingly, the present study proposes a generalized reverse current-voltage (I-V) plot which enables the series resistance R, barrier heightφ, and ideality factor n of a reverse biased Schottky contact to be extracted from a single set of I-V measurements. A theoretical derivation of the proposed approach is presented and a series of validation tests are then performed. The results show that the proposed-method is capable of extracting reliable estimates of the contact parameters even in the presence of experimental noise.
