An experimental procedure is presented for the determination of the barrier height of metal-semiconductor contacts that avoids the use of the so called “ideality factor” n, common in the fit of experimental IV-data. We choose the commonly experienced case where the deviation of n from 1 is caused by a combination of recombination current contribution and the influence of series resistance. These effects are introduced into a computer fitting to the experimental forward IV data. We report on very good fitting of theory and experiment. Also, the discrepancy in the φ B values determined by ordinary deduction from IV measurements and those obtained from photoelectric measurements practically vanishes if our procedure is used.
