Abstract :
Effect of the thermal annealing (300-380degC, 5 min) of Ti/Au barriers to sulfur treated n-GaAs (100) on its parameters was studied. It was shown that the annealing temperature influences the height of barrier, the current-voltage ideality factor and the reverse voltage at 100 muA. The optimal annealing temperature was defined.
