ABSTRACT
It is shown that by using the forward current density-voltage (J-V) characteristics of a Schottky diode, a plot of d(V)/d(ln J) vs J and a plot of the function H(J) vs J, where H(J)≡V-n(kT/q)ln(J/A**T2), will each give a straight line. The ideality factor n, the barrier height [lowercase_phi_synonym]B, and the series resistance R of the Schottky diode can be determined with one single I-V measurement. This procedure has been used successfully to study thermal annealing effects of W/GaAs Schottky contacts.

    Effect of annealing on the electrical properties of 50 nickel Schottky contacts formed on a single 4 H-SiC wafer has been studied. It is shown that annealing at 200°C for 1 h favors homogenization of the metal-semiconductor heterointerface, which leads to a narrower scatter of such contact...

    Electrical properties of rare-earth metal contacts on AlGaN/GaN heterostructure were interpreted in terms of the changes in microstructure and chemical bonding state. When the contacts were annealed under oxygen ambient at 500 °C, the Schottky barrier height increased from 0.56 to 1.10 eV for...
