This letter shows how the splitting of the forward and reverse current/voltage curves of a Gunn diode may be interpreted in terms of different models of contact damage, and proposes a simple test technique to obtain a quantitative measure of contact quality. Experimental verification of this technique is presented, showing a correlation between device efficiency and a contact parameter ß.
